Hi!
Hoping someone can give me that “ah ha!” moment that I’m so desperately
craving after pouring over the documentation, mailing lists and various
forum posts.
I want to move from BackupPC’s default schedule to keeping ~1 month’s worth
of backups, but I cannot fathom if I should:
- Do a full backup every day and keep 30 of them
- Do a full backup every week and keep 4 of them, with
incrementals in between
- Do a full backup each month and keep 30 incrementals.
BackupPC is so efficient with storage and transferring only what is needed
between backups that I don’t understand the difference between the three
approaches. All backups can be browsed like full backups, BackupPC only
ever transfers files it doesn’t have, all storage is deduplicated and rsync
can detect changes, new files and deletions, so why does it matter? I am
using rsync (over SSH), network speed and reliability is good and the
drives are all SSD.
The settings I currently have are:
FullPeriod 6.97
FullKeepCnt 4
IncrPeriod 0.97
IncrKeepCnt 24
I **think** this will give me 4 full backups with incrementals in between,
but I think I could have equally have gone with:
FullPeriod 30
FullKeepCnt 1
IncrPeriod 0.97
IncrKeepCnt 29
I don’t understand what is meant by a “filled backup” either.
Thanks for any clarity/help in advance!
Regards
Jamie
