Re: [BackupPC-users] Full and Incrementals Backup question
2010-04-09 10:01:39
Oh.. yes... I have not read "IncreLevels". Thanks a lot.
Also...
FullPeriod : 10 (but I force it by crontab on friday night)
FullKeepCnt : 2
IncrPeriod : 1
IncrKeepCnt : 8
IncrLevel : 1, 2, 3
Blackout on weekend (and during week on 7am to 10 pm)
That's an example : I am on 30/04.
DELETE - 09/04 - Level 0 - Friday : Full
DELETE - 12/04 - Level 1 - Monday : Incr - Depends on the level 0
DELETE - 13/04 - Level 2 - Tuesday : Incr - Depends on the level 1
DELETE - 14/04 - Level 3 - Wednesday : Incr - Depends on the level 2
DELETE - 15/04 - Level 4 - Thursday : Incr - Depends on the level 3
KEEP - 16/04 - Level 0 - Friday : Full (keep because incr depends it)
KEEP - 19/04 - Level 1 - Monday : Incr - Depends on the level 0
KEEP - 20/04 - Level 2 - Tuesday : Incr - Depends on the level 1
KEEP - 21/04 - Level 3 - Wednesday : Incr - Depends on the level 2
KEEP - 22/04 - Level 4 - Thursday : Incr - Depends on the level 3
KEEP - 23/04 - Level 0 - Friday : Full
KEEP - 26/04 - Level 1 - Monday : Incr - Depends on the level 0
KEEP - 27/04 - Level 2 - Tuesday : Incr - Depends on the level 1
KEEP - 28/04 - Level 3 - Wednesday : Incr - Depends on the level 2
KEEP - 29/04 - Level 4 - Thursday : Incr - Depends on the level 3
KEEP - 30/04 - Level 0 - Friday : Full
And if I am on 28/04 (for example) I keep all Backup on 09/04 to 15/04)
That's correct ? (is complicated ^^')
Thanks a lot :o)
