v9 maintenance jobs

[hyvokar]

Hi!

I have couple of questions concerning v9 maintenance jobs.

I mainly use reverse incremental backup mode. If I have understood correctly (have I?), I need to take active full backup periodically to avoid possible backup chain corruption.
V9 introduced full backupfile compact and storage-level corruption guard.

1) Will backupfile defragment and corruption guard help against backup chain corruption (so I would not need to use active full backup)?
2) Will active full backup compact and defragment the full backup file?
3) ..or do I need to use all three of these?

Hi,
1) Yes it helps, but I would still recommend SureBackup for full recoverability testing.
2) New active fulls don`t need the maintenance.
3) It depends on the Surebackup vs. Active fulls choice.

Health check protects against storage bit rot, while SureBackup makes sure VMs stored in the backup are recoverable, so it is recommended to use both as well as compact operation to defragment the backup file. If all three are used, active fulls are typically required only in cases listed in the thread Nikita has referred to above.

Correct. I don't see any technical reasons to do Active Fulls with v9 except when backup storage is too weak on IOPS for forever-incremental backups (in which case streaming workload of Active Full will allow backups to finish faster), or to perform said backup files maintenance over a weekend.

Non-technical reasons is a separate topic (sometimes it can be required by company policy, some people feel more confident about such restore points, etc.)
