Hello,
I'm new to Bacula and need some help with scheduling, pools and well,
backup strategy in general. I will be backing up three clients
(including the server running Bacula) and one 800GB LTO-4 tape drive,
and there will be 'someone' for changing tapes.
The basic idea of the backup strategy is 4 weekly tapes and 1 monthly
tape per month:
* every Friday a tape is changed
* if it's a first Friday in month, a new tape should be inserted and
it should be auto-labeled with the previous month's name
* on every other Friday, the next recyclable weekly tape should be
inserted
* every Friday a full backup should be performed
* every other weekday an incremental backup should be performed
* weekly tapes should be recycled after 4 weeks
* monthly tapes should be stored separately for at least one year
To further clarify things, this is what want (the asterisk marks a
Friday / changing tapes):
Date Tape inserted Backup level
* 6.1.2012 DECEMBER Full
7.1.2012 DECEMBER none
8.1.2012 DECEMBER none
9.1.2012 DECEMBER Incremental
10.1.2012 DECEMBER Incremental
11.1.2012 DECEMBER Incremental
12.1.2012 DECEMBER Incremental
* 13.1.2012 WEEK_1 Full
14.1.2012 WEEK_1 none
15.1.2012 WEEK_1 none
16.1.2012 WEEK_1 Incremental
17.1.2012 WEEK_1 Incremental
18.1.2012 WEEK_1 Incremental
19.1.2012 WEEK_1 Incremental
* 20.1.2012 WEEK_2 Full
21.1.2012 WEEK_2 none
22.1.2012 WEEK_2 none
23.1.2012 WEEK_2 Incremental
24.1.2012 WEEK_2 Incremental
25.1.2012 WEEK_2 Incremental
26.1.2012 WEEK_2 Incremental
* 27.1.2012 WEEK_3 Full
28.1.2012 WEEK_3 none
29.1.2012 WEEK_3 none
30.1.2012 WEEK_3 Incremental
31.1.2012 WEEK_3 Incremental
1.2.2012 WEEK_3 Incremental
2.2.2012 WEEK_3 Incremental
* 3.2.2012 JANUARY Full
4.2.2012 JANUARY none
5.2.2012 JANUARY none
6.2.2012 JANUARY Incremental
7.2.2012 JANUARY Incremental
8.2.2012 JANUARY Incremental
9.2.2012 JANUARY Incremental
* 10.2.2012 WEEK_4 Full
11.2.2012 WEEK_4 none
12.2.2012 WEEK_4 none
13.2.2012 WEEK_4 Incremental
14.2.2012 WEEK_4 Incremental
15.2.2012 WEEK_4 Incremental
16.2.2012 WEEK_4 Incremental
* 17.2.2012 WEEK_1 Full
18.2.2012 WEEK_1 none
19.2.2012 WEEK_1 none
20.2.2012 WEEK_1 Incremental
21.2.2012 WEEK_1 Incremental
22.2.2012 WEEK_1 Incremental
23.2.2012 WEEK_1 Incremental
....
So I defined a 'weekly' pool and a 'monthly' pool:
Pool {
Name = Weekly_Tape
Pool Type = Backup
Recycle = yes
AutoPrune = yes
Volume Retention = 4 weeks
Volume Use Duration = 1 week
}
Pool {
Name = Montly_Tape
Pool Type = Backup
Recycle = yes
AutoPrune = yes
Volume Retention = 1 year
Volume Use Duration = 1 week
Label Format = "${Months[${Month}]}"
}
But I'm not quite sure how to implement my strategy in 'Schedule'...
Right now I have this:
Schedule {
Name = "WeeklyCycleTape"
Run = Level=Full Pool=Montly_Tape 1st fri at 23:05
Run = Level=Full Pool=Weekly_Tape 2nd-5th fri at 23:05
Run = Incremental mon-thu at 23:05
}
But that would probably request a tape from the 'weekly' pool every
Monday - Thursday ...
Is it possible to do what I want with Bacula scheduling?
