So I decided to switch my backups to ext4 by creating a new server and migrating.
- Created a new VPS server
- Attached ext block storage to it mounted it as /backups
- Installed in enhance, with DNS, and backup roles.
- Started server move process.
Most sites failed do to permission "Data migration failure: internal: Backup rsync transfer failed: rsync: [sender] opendir "/backups/2c3d6a7b-b7c2-4605-9015-67f1318229ac/snapshot-1739695037490/email" failed: Permission denied (13)"
Before migrate I did run update && apt install ecp-core and v12-upgrade fix-backup-permissions /backups
I did notice that owner permissions on sub folders fluctuate between 2063 and 2c3d6a7bb7c24605901567f1318229ac. So maybe the v12-upgrade fix-backup-permissions /backups is not updating all snapshots.
I did remove the snapshots with the wrong file permission and it let me migrate to the new backup sever.
