Hello, I am sorry if this is a question that was asked before. I searched around a bit and couldn’t find any similar questions, nor could I find any documentation that answered my questions.
I am running XCP-ng with Xen Orchestra for my homelab, however when trying to debug some behaviour and get a better understanding of how everything works I noticed a couple different interesting behaviours:
Key backups, key backups as far as I understand mean that it is kept for longer term storage, so if my understanding is correct, assuming I make 1 backup every 4 hours of the day, retain 12 backups in the schedule, and retain 3 days of backups, 4 weeks of backups and 6 months of backups this should happen:
[(Key) Full Backup 1]→[Delta 1]→[Delta 2]→[Delta 3]→…→[Delta 14] For daily.
When the day ends:
[(Key) Full Backup 1]→[(Key) Daily Backup 1]→[Delta 1]→…→[Delta 14] For daily.
And then once that day ends we have this:
[(Key) Full Backup 1]→[(Key) Daily Backup 1]→[(Key) Daily Backup 2]→[Delta 1]→…→[Delta 14] For daily.
So if my understanding is correct a key backup is purely a backup that would be stored long(er) term?
And so when the week would end and a new weeks starts, all daily backups of last week would be squashed and merged into a new key backup that contains everything for the week?
