Deleting incremental backups
-
Good Morning, I am using XOCE Xen Orchestra, commit adc5b, Master, commit adc5b. I have backups failing on one of my servers because of insufficient free space on the NFS remote. If, in the backup/restore page I delete some of the older backups, will that break the chain or will it use merge to preserve the integrity of the chain?
Thanks. -
@frank-s This depends on what type of backup you're running, if you're using Delta or CR then you could cause issues.
If you're using full backups, then each would be distinct from each other.
-
@DustinB These are delta backups. I'm just wondering if the delete button in the restore page is just that - delete which would break the chain or if a merge is used which would preserve the chain.
-
@frank-s Wouldn't it be easier to adjust your job so you're not keeping so many backups? This way the system will automatically clean up any jobs and help to keep your SR sufficiently freed up?
-
@DustinB Yes, by reducing the retention. I have thought about that but I'm afraid that the merge might happen after the backup and because there is insufficient space the backup would fail again. I don't want the system to force a full backup because I follow this backup with a mirror backup to s3 and the internet upload is limited in speed.
-
@frank-s You might have no choice but to delete your backup chains and reduce the retention.
It seems like you're really too constrained by your backup repo's capacity.

@DustinB OK. I think I'm between a rock and a hard place! Thanks for the advice.
