@TechGrips Sorry, there is no quick test to be sure the VM is not corrupted. The usual way would be to make a healthcheck. We cannot be sure everything is ok as it concerns multiple tar linked to each other. If it keeps warning you on the same backups, it may be due to a faulty parent. You would need for this to create a new chain of snapshot

@Danp Thanks... Just ticked that off and they are migrating. I'll try backup again but something tells me the backup issue will still persist. I'll send logs once that fails.

@DustinB said in XOA Retention - entries must be sorted in asc order: I've since removed the entries in the long-term-retention field, and will validate if the backup succeeds here in a bit. Once removing the LTR records, backups succeeded. @olivierlambert said in XOA Retention - entries must be sorted in asc order: Hi, It's a known issue that will be fixed this month Good to know, thanks!
