You disturb me ;-) ! I summarize to be sure I understand. Full : 600 GB Data modify by day : 10 GB
------- IncrLevel = 1 M | T | W | T | F | S | S | <- Day I | I | I | I | F | - | - | <- Backup type 1 | 1 | 1 | 1 | 0 | - | - | <- Level 10| 20| 30| 40|600| - | - | <- DATA COPY BY DAY (GB) ------- IncrLevel = 1, 2, 3, 4 M | T | W | T | F | S | S | <- Day I | I | I | I | F | - | - | <- Backup type 1 | 2 | 3 | 4 | 0 | - | - | <- Level 10| 10| 10| 10|600| - | - | <- DATA COPY BY DAY (GB) ------- With IncrLevel 1, 2, 3, 4 i'm sure that the incrlevel 3 will be not delete if 2, 1 and 0 exist. With IncrLevel 1, I'm not sure about that... ------- FullPeriod = 2 IncrPeriod = 8 Also I keep two weeks of backup (and I'm sure no backup will be not delete) ------- ------- ------- Thanks a lot :-) > Message du 17/04/10 à 08h50 > De : "Luis Paulo" <[email protected]> > A : [email protected] > Copie à : "General list for user discussion questions and support" > <[email protected]> > Objet : Re: [BackupPC-users] Full and Incrementals Backup question > > Inno, > If files are all different, and you modify 10GB every day keeping the 600 > total, I think (pretty sure) that yes, on the 4th you'll have the original > 600GB plus the 40GB differences. > That with incrementals. > > With fulls every day, you'll have just 600GB every day, total on the pool > (we are not minding about compression), after the cleanup. > > (Really hope Les don't mind me saying what he said with other words.
