Once I've set delta backups with backup retention equaling to 14 on XoCE VM, storing them on remote NFS storage. After few months I had spin up new virtual machine for XO and mounted same NFS storage, set up same backup schedule.
Now most of my VM's are having 28 restore points, 14 made by the old XoCE installation, 14 by new one.
For new ones retention works well, but it doesn't delete those made by old installation, though it recognizes them as restore points.
Can I safely remove old backups? New delta's dont require them to recover entire VM ?
