Why EXACTLY do backups get status "Marked for deletion. No operations can be done.."?
I've been usin Acronis BU 11.5 for a long time but I've never quite understood exactly what does it mean when in my G-F-S backup scheme Vault there very often out of the blue emerges those black markings on the Daily backup archives stating that "This backup is marked for deletion. No operation can be performed on backup"? What's the reason for the marked status?
I don't now remember that happening to any Weekly (differential) backups but am not sure.
I remember having those markings/locks active many times on Daily/Incremental backups and not having Weekly nor Monthly backup taken after them, so does it mean that my whole catalog is ruined since the latest marked backup?
I recently had to restore my whole PC as DISK restore but it failed every time, but I managed to restore all my files using VOLUME restore option. My guess was that it was due to having a few Incremental backups marked for deletion. I can't remember if there were any Weekly backups taken after those "locked/marked" Daily backups., but anyway the DISK restoring failed.
So does a "marked for deletion" backup mean it's a corrupted backup? The weird thing is that some of the subsequent daily backups after the marked ones are NOT marked. Since the marked backups cannot be restored files from, then it logically appears to me that they indeed are corrupted. Or what?
And if the marked backups can't be restored files/volumes/disks from, then it shouldn't (?) be possible to restore also from the subsequent Daily backups? Or what, again?
And why doesn't Acronis just delete them? Even if I just took Full BU because I again have marked older Incremental backups, Acronis still doesn't remove them. What is it keeping them for? So should I always take a full backup after marked backups appearing and delete all the old ones or what measures should I take?
Thank You in advance!
