Pbm Delete backup

I’m using pbm version 2.2.1 and unable to delete the backups.

[mongod@tora-pl211 ~]$ pbm delete-backup 2024-03-16T01:00:02Z
Are you sure you want delete backup(s)? [y/N] y
Waiting for delete to be done ..Error: deleting: unable to delete: backup is a base for '2024-03-16T13:31:43 - 2024-04-02T11:22:05'

I had to delete the PITR backups using “pbm delete-pitr --older-than=” command before deleting the full logical backup.
Is this a bug in 2.2.1?

@aranjith0

Thanks for reaching out to us here.

Basically, there are certain conditions on backup type due to which backups cannot be deleted by pbm delete-backup command.

  1. A backup that is the base for any point-in-time recovery and with point-in-time recovery time ranges derived from it.

  2. The most recent backup, if Point-in-Time Recovery is enabled and there are no oplog slices following this backup yet.

It seems the backup you are trying to delete is used by the PITR [‘2024-03-16T13:31:43 - 2024-04-02T11:22:05’]

I had to delete the PITR backups using “pbm delete-pitr --older-than=”

Yes, in that case you have to rely on above command. Also, you can try pbm cleanup --older-than … in order to remove both backup and pitr slices together.

Reference:- Delete backups - Percona Backup for MongoDB

This doesn’t seems to be a bug rather its a behaviour!!

Let us know if this brings some clarity or if you having any further questions.

When i try to remove both backup and pitr slices together older than 10days using the command pbm cleanup --older-than=10d --yes
But it shows nothing to delete.

@aranjith0

Can you please confirm the pbm list output as well in order to verify the existing backups ?

Did you also tried with exact timestamp condition as below. Can you confirm if this is running fine ?

pbm cleanup --older-than=%Y-%M-%D --yes
pbm cleanup --older-than=%Y-%M-%DT%H:%M:%S --yes
  • %Y-%M-%DT%H:%M:%S (for example, 2023-04-20T13:13:20) or
  • %Y-%M-%D (2023-04-20)

Please also share the below logs to check about some events.

pbm logs --event=pitr
pbm logs --event=delete

Hi Anil,

The command doesn’t delete anything. whereas this command works fine. ( pbm cleanup --older-than=%Y-%M-%DT%H:%M:%S --yes)
