Incremental Backup Question

[Velocity1192]

Hello,

I'm attempting to implement Xen Orchestra Incremental Backups in the v5 interface (not seeing it in v6)

Will the v6 display a picture or table when creating jobs and schedules like https://docs.xen-orchestra.com/backups-and-dr/backup-types/incremental_backups - I think it's much cleaner and clearer about how the settings are configured.

What I'm trying to configure is having the full backup occur on a specific day of the week like suggested.
and on Sunday Week 5 - Weeks 1 and 2 are deleted.

Do I need two separate schedules one to complete the Full Backup and another for the deltas? Would the retention be 2 for full and 12 for the delta?

Or is it do I just create one schedule and enable it on a Sunday and it can't be enabled in advance?

Thanks,
Andrew

Hi, @Velocity1192 .

On v6 first: creating and editing backup jobs still happens in XO 5 for now, XO 6 shows the jobs but doesn't create them yet (https://docs.xen-orchestra.com/backups-and-dr/backups-in-xo6).

For the schedule, @abudef asked almost the same question earlier this year. @Pilow's answer there is clearer than anything I'd write: https://xcp-ng.org/forum/post/104108.
As I read it, you either use one daily schedule plus the "Full backup interval" setting (the full lands N runs after the chain starts), or two schedules on the same job with "Force full backup" ticked on the Sunday one.
That second way is how you get to pick the day, and he says not to mix the two. One thing to expect, from @Danp in another thread (https://xcp-ng.org/forum/post/91943) : the oldest backup is always a full and old deltas get merged into it, so for a while you'll see two fulls on the remote rather than weeks 1 and 2 being deleted. I don't think the scheduler can say "every other Sunday". I might be wrong there; someone who runs this kind of plan may know a trick.
