`pbm` commands¶

pbm CLI is the command line utility to control the backup system. This page describes pbm commands available in Percona Backup for MongoDB.

For how to get started with Percona Backup for MongoDB, see Initial setup.

pbm backup¶

Creates a backup snapshot and saves it in the remote backup storage.

The command has the following syntax:

$ pbm backup [<flags>]

For more information about using pbm backup, see Starting a backup

The command accepts the following flags:

Flag	Description
`-t`, `--type`	The type of backup. Supported values: physical, logical (default), incremental, external. When not specified, Percona Backup for MongoDB makes a logical backup.
`--base`	For incremental backups only. Set the backup as the base and start tracking the incremental backup history to calculate and save the difference in data blocks for subsequent incremental backups.
`--compression`	Create a backup with compression. Supported compression methods: `gzip`, `snappy`, `lz4`, `s2`, `pgzip`, `zstd`. Default: `s2` The `none` value means no compression is done during backup.
`--compression-level`	Configure the compression level from 0 to 10. The default value depends on the compression method used.
`--num-parallel-collections`	Sets the number of collections to process in parallel during a specific logical backup. When undefined, `pbm-agent` processes the number of parallel collections defined for the `backup.numParallelCollections` configuration parameter. If that is undefined, the default number of collections to process in parallel is the half of the number of logical CPUs. Available starting with version 2.7.0.
`-o`, `--out=text`	Shows the output format as either plain text or a JSON object. Supported values: `text`, `json`
`--wait`	Wait for the backup to finish. The flag blocks the shell session.
`--wait-time`	The time to wait for PBM to report the status of the command execution. Use this flag together with the `--wait` flag. You can specify the duration in minutes or hours (e.g. 5m, 1h). When not set, PBM waits till the command executes. If it takes longer than the defined waiting time to execute the command, PBM prints the `Operation is in progress. Check pbm status and logs` error message and unblocks the shell session. The `pbm-agent` continues to execute the command enabling you to track its progress via the `pbm status` command. Available starting with version 2.6.0.
`-l`, `--list-files`	For external backups only. Shows the list of files per node to copy.
`--ns="database.collection"`	Makes a logical backup of the specified namespace - the database and collection(s). To back up all collections in the database, specify the value in the `--ns="database."` format. Starting with version 2.8.0, you can pass multiple namespaces as a comma-separated list for the backup. The format is `ns=db1.,db2.coll2,db3.coll1,db3.collX` .

JSON output

{
  "name": "<backup_name>",
  "storage": "<my-backup-dir>"
}

pbm backup-finish¶

Closes the backupCursor and finishes the external backup. Must be run after running pbm backup -t external. To learn more, refer to API for snapshot-based physical backups.

The command has the following syntax:

$ pbm backup-finish [backup-name]

pbm cancel-backup¶

Cancels a running backup. The backup is marked as canceled in the backup list.

The command accepts the following flags:

Flag	Description
`-o`, `--out=text`	Shows the output format as either plain text or a JSON object. Supported values: `text`, `json`

JSON output

{
  "msg": "Backup cancellation has started"
}

pbm cleanup¶

Deletes outdated backup snapshots and point-in-time recovery oplog slices.

The command has the following syntax:

pbm cleanup [<flags>]

The command accepts the following flags:

Flag	Description
`--older-than=TIMESTAMP`	Deletes backups older than date / time specified in the format: - `%Y-%M-%DT%H:%M:%S` (e.g. 2020-04-20T13:13:20), - `%Y-%M-%D` (e.g. 2020-04-20), - `XXd` (e.g. 30d). Only days are supported
`-w`, `--wait`	Wait for the cleanup to finish. The flag blocks the shell session
`--wait-time`	The time to wait for PBM to report the status of the command execution. Use this flag together with the `--wait` flag. You can specify the duration in minutes or hours (e.g. 5m, 1h). When not set, PBM waits till the command executes. If it takes longer than the defined waiting time to execute the command, PBM prints the `Operation is in progress. Check pbm status and logs` error message and unblocks the shell session. The `pbm-agent` continues to execute the command enabling you to track its progress via the `pbm status` command. Available starting with version 2.6.0.
`-y`, `--yes`	Cleans up the data storage without asking for a user’s confirmation
`--dry-run`	Checks for the old data to be deleted without deleting it. Allows to verify what data to delete

pbm config¶

Sets, changes or lists Percona Backup for MongoDB configuration.

The command has the following syntax:

$ pbm config [<flags>] [<key>]

The command accepts the following flags:

Flag	Description
`--force-resync`	Resync backup list with the current storage
`--list`	List current settings
`--file=FILE`	Upload the config information from a YAML file
`--set=SET`	Set a new config option value. Specify the option in the `<key.name=value>` format.
`-o`, `--out=text`	Shows the output format as either plain text or a JSON object. Supported values: text, json
`-w`, `--wait`	Wait for resync of the backup list with the storage to finish. You can only use this flag together with the `--force-resync` flag.
`--wait-time`	The time to wait for PBM to report the status of the resync execution. Use this flag together with the `--wait` flag. You can specify the duration in minutes or hours (e.g. 5m, 1h). When not set, PBM waits till the command executes. If it takes longer than the defined waiting time to execute the command, PBM prints the `Operation is in progress. Check pbm status and logs` error message and unblocks the shell session. The `pbm-agent` continues to execute the command enabling you to track its progress via the `pbm status` command. Available starting with version 2.6.0.

pbm delete-backup¶

Deletes the specified backup snapshot or all backup snapshots that are older than the specified time with the option to filter by specific type. The command deletes backups that are not running regardless of the remote backup storage being used.

The following is the command syntax:

$ pbm delete-backup [<flags>] [<name>]

The command accepts the following flags:

Flag	Description
`--older-than=TIMESTAMP`	Deletes backups older than date / time specified in the format: - `%Y-%M-%DT%H:%M:%S` (e.g. 2023-04-20T13:13:20) or - `%Y-%M-%D` (e.g. 2023-04-20)
`--type=TYPE`	Deletes backups of the specified type. Must be used together with the `-older-than` flag. Available starting with version 2.4.0
`--force`	Forcibly deletes backups without asking for user’s confirmation. Deprecated. Use the `--yes` flag instead.
`-y`, `--yes`	Deletes backups without asking for user’s confirmation
`--dry-run`	Prints the list of backup snapshots to be deleted without deleting them. You can use the flag to check what exactly will be deleted. Available starting with version 2.4.0.

pbm delete-pitr¶

Deletes oplog slices produced for Point-in-Time Recovery.

The command has the following syntax:

pbm delete-pitr [<flags>]

The command accepts the following flags:

Flag	Description
`-a`, `--all`	Deletes all oplog slices. Deprecated. Use the `--older-than flag instead`
`--older-than=TIMESTAMP`	Deletes oplog slices older than date / time specified in the format: - `%Y-%M-%DT%H:%M:%S` (e.g. 2020-04-20T13:13:20) or - `%Y-%M-%D` (e.g. 2020-04-20) When you specify a timestamp, Percona Backup for MongoDB rounds it down to align with the completion time of the closest backup snapshot and deletes oplog slices that precede this time. Thus, extra slices remain. This is done to ensure oplog continuity. To illustrate, the PITR time range is `2021-08-11T11:16:21 - 2021-08-12T08:55:25` and backup snapshots are: `2021-08-12T08:49:46Z 13.49MB [restore_to_time: 2021-08-12T08:50:06]` `2021-08-11T11:36:17Z 7.37MB [restore_to_time: 2021-08-11T11:36:38]` Say you specify the timestamp `2021-08-11T19:16:21`. The closest backup is `2021-08-11T11:36:17Z 7.37KB [restore_to_time: 2021-08-11T11:36:38]`. PBM rounds down the timestamp to `2021-08-11T11:36:38` and deletes all slices that precede this time. As a result, your PITR time range is `2021-08-11T11:36:38 - 2021-08-12T09:00:25`. NOTE: Percona Backup for MongoDB doesn’t delete the oplog slices that follow the most recent backup. This is done to ensure point in time recovery from that backup snapshot. For example, if the snapshot is `2021-07-20T07:05:23Z [restore_to_time: 2021-07-21T07:05:44]` and you specify the timestamp `2021-07-20T07:05:45`, Percona Backup for MongoDB deletes only slices that were made before `2021-07-20T07:05:23Z`.
`--force`	Forcibly deletes oplog slices without asking a user’s confirmation. Deprecated. Use the `-y`/`--yes` flag instead.
`-o`, `--out=json`	Shows the output as either the plain text (default) or a JSON object. Supported values: `text`, `json`.
`--yes`	Deletes backups without asking for user’s confirmation
`--dry-run`	Prints the list of oplog slices to be deleted without deleting them. You can use the flag to check what exactly will be deleted. Available starting with version 2.4.0.
`-w`, `--wait`	Wait for the deletion operation to complete.
`--wait-time`	The time to wait for PBM to report the status of the command execution. Use this flag together with the `--wait` flag. You can specify the duration in minutes or hours (e.g. 5m, 1h). When not set, PBM waits till the command executes. If it takes longer than the defined waiting time to execute the command, PBM prints the `Operation is in progress. Check pbm status and logs` error message and unblocks the shell session. The `pbm-agent` continues to execute the command enabling you to track its progress via the `pbm status` command. Available starting with version 2.6.0.

In progress - A backup is running
Canceled - A backup was canceled
Error - A backup was finished with an error
No status means a backup is complete

As of version 1.4.0, only successfully completed backups are listed. To view currently information about a running or a failed backup, run pbm status.

When Point-in-Time Recovery is enabled, the pbm list also provides the list of valid time ranges for recovery and point-in-time recovery status.

The command has the following syntax:

$ pbm list [<flags>]

The command accepts the following flags:

Flag	Description
`--restore`	Shows last N restores. Starting with version 2.0, the output shows restore names instead of backup names, as multiple restores can be done from a single backup.

pbm oplog-replay¶

Allows to replay the oplog on top of any backup: logical, physical, storage level snapshot (like EBS-snapshot) and restore it to a specific point in time.

To learn more about the usage, refer to Point-in-Time Recovery oplog replay.

The command has the following syntax:

$ pbm oplog-replay [<flags>]

The command accepts the following flags:

Flag	Description
`start=timestamp`	The start time for the oplog replay.
`end=timestamp`	The end time for the oplog replay.
`--replset-remapping`	Maps the replica set names for the oplog replay. The value format is `to_name_1=from_name_1,to_name_2=from_name_2`.
`-w`, `--wait`	Wait for the oplog replay operation to complete.
`--wait-time`	The time to wait for PBM to report the status of the oplog replay execution. Use this flag together with the `--wait` flag. You can specify the duration in minutes or hours (e.g. 5m, 1h). When not set, PBM waits till the command executes. If it takes longer than the defined waiting time to execute the command, PBM prints the `Operation is in progress. Check pbm status and logs` error message and unblocks the shell session. The `pbm-agent` continues to execute the command enabling you to track its progress via the `pbm status` command. Available starting with version 2.6.0.

pbm profile add¶

Saves an external storage configuration to PBM. This information is defined via configuration profiles.

To learn more about configuration profiles, see Multiple storages for backups.

The command has the following syntax:

$ pbm profile add [<flags>] <profile-name> <path/to/profile.yaml>

The command accepts the following flags:

Flag	Description
–sync	Add a profile defining an external storage and sync the backup list from this storage
–wait	Wait for the profile to be added. The flag blocks the shell session.
`--wait-time`	The time to wait for PBM to report the status of adding the profile and backup sync. Use this flag together with the `--wait` flag. You can specify the duration in minutes or hours (e.g. 5m, 1h). When not set, PBM waits till the command executes. If it takes longer than the defined waiting time to execute the command, PBM prints the `Operation is in progress. Check pbm status and logs` error message and unblocks the shell session. The `pbm-agent` continues to execute the command enabling you to track its progress via the `pbm status` command. Available starting with version 2.6.0.
-o, –out=text	Shows the output format as either plain text or a JSON object. Supported values: `text`, `json`

pbm profile remove¶

Removes the specified configuration profile from PBM.

The command has the following syntax:

$ pbm profile remove <profile-name> [<flags>]

The command accepts the following flags:

Flag	Description
`--wait`	Wait for the profile to be removed. The flag blocks the shell session.
`--wait-time`	The time to wait for PBM to report the status of the profile removal. Use this flag together with the `--wait` flag. You can specify the duration in minutes or hours (e.g. 5m, 1h). When not set, PBM waits till the command executes. If it takes longer than the defined waiting time to execute the command, PBM prints the `Operation is in progress. Check pbm status and logs` error message and unblocks the shell session. The `pbm-agent` continues to execute the command enabling you to track its progress via the `pbm status` command. Available starting with version 2.6.0.

$ pbm profile sync <profile-name> [<flags>]

The command accepts the following flags:

Flag	Description
`--all`	Syncs backup lists from all the storages.
`--clear`	Clears the backup list from the storage. To clear the backup list from a specific storage, pass the profile name. When used with `--all`, clears backup lists from all storages.
`--wait`	Wait for the profile to be synced. The flag blocks the shell session.
`--wait-time`	The time to wait for PBM to report the status of the profile sync. Use this flag together with the `--wait` flag. You can specify the duration in minutes or hours (e.g. 5m, 1h). When not set, PBM waits till the command executes. If it takes longer than the defined waiting time to execute the command, PBM prints the `Operation is in progress. Check pbm status and logs` error message and unblocks the shell session. The `pbm-agent` continues to execute the command enabling you to track its progress via the `pbm status` command.

pbm restore¶

Restores database from a specified backup / to a specified point in time. Depending on the backup type, makes either logical, physical, or a snapshot-based restore.

The command has the following syntax:

$ pbm restore [<flags>] [<backup_name>]

For more information about using pbm restore, see Restoring a backup.

The command accepts the following flags:

Flag	Description
`--external`	Indicates the backup as the one made outside PBM (for example, snapshot-based)
`--time=TIME`	Restores the database to the specified point in time. Available for logical restores and if Point-in-time recovery is enabled.
`-w`	Wait for the restore to finish. The flag blocks the shell session.
`--wait-time`	The time to wait for PBM to report the status of the restore execution. Use this flag together with the `--wait` flag. You can specify the duration in minutes or hours (e.g. 5m, 1h). When not set, PBM waits till the command executes. If it takes longer than the defined waiting time to execute the command, PBM prints the `Operation is in progress. Check pbm status and logs` error message and unblocks the shell session. The `pbm-agent` continues to execute the command enabling you to track its progress via the `pbm status` command. Available starting with version 2.6.0.
`-o`, `--out=text`	Shows the output format as either plain text or a JSON object. Supported values: `text`, `json`
`--base-snapshot`	Restores the database from a specified backup to the specified point in time. Without this flag, the most recent backup preceding the timestamp is used for point in recovery. Available in Percona Backup for MongoDB starting from version 1.6.0. In version 2.3.0, this flag is optional for point-in-time recovery from physical backups. In version 2.2.0, this flag is mandatory for making a point-in-time recovery from physical backups. Without it, PBM looks for a logical backup to restore from.
`--replset-remapping`	Maps the replica set names for the data restore / oplog replay. The value format is `to_name_1=from_name_1,to_name_2=from_name_2`
`--ns=<database.collection>`	Restores the specified namespace(s) - databases and collections. To restore all collections in the database, specify the values as `--ns=<database.>`. The `--ns` flag accepts several namespaces as the comma-separated list. For example, `--ns=db1.,db2.coll2,db3.coll1,db3.collX`
`--with-users-and-roles`	Restores users and roles created in custom databases during selective restore. Use this flag with the `--ns` flag. Available starting with version 2.5.0.
`-c`, `--config`	The path to the `mongod.conf` file
`--num-parallel-collections`	Sets the number of collections to process in parallel during a specific logical restore. When undefined, `pbm-agent` processes the number of parallel collections defined for the `restore.numParallelCollections` configuration parameter. If that is undefined, the default number of collections is the half of the number of logical CPUs. Available starting with version 2.7.0.
