Hi,
We are using bacula 2.2.6 with a disk based backup solution. 3 Months into
testing, backups & restores are working.
Here goes the problem : we need to backup 750Gb of data (22 server samba
shares) and guarantee one (maybe two) months of restore data just in case
somebody moves a directory, loses a file, wants lask week's file etc... The
samba shares are basically full of doc/xls/pdf etc...
The backup is a 2 To raid5 disk solution. I'm a bit worried about keeping
control over volumes and disk space. I don't want the volumes to fill up any
further than 1.8To while keeping one or 2 months of history.
We've resolved one problem regarding size by using the compress option :o)
So, our bacula.conf strategy is :
• one full backup per month, plus incremental every other day (no
differential).
• one volume per share (so that we can keep a eye on a fast growing
volume).
• keeping job/file/volume retention to 1 month (maybe 2).
But the volumes just grow... and grow. I've 'volume updated' for retention
periods but the auto-pruning doesn't seem to reduce volume size. For example
after the 2nd month's full backup I thought the volume would be reduced in size
by the 1st month"s full backup size (it's outside the retention period).
Schedule, Volume & Client syntax are :
Schedule {
Name = "WeeklyCycle"
Run = Full 1st sun at 00:05
Run = Incremental mon-sat at 23:05
#Run = Differential 2nd-5th sun at 23:05
#Run = Incremental mon-sun at 23:05
}
Client {
Name = pool01-fd
Address = 192.168.x.y
FDPort = 9102
Catalog = MyCatalog
Password = "xxx"
File Retention = 1 month # 30 days
Job Retention = 1 months # 30 days
AutoPrune = yes # Prune expired Jobs/Files
}
Pool {
Name = Pool01
Pool Type = Backup
Recycle = yes # Bacula can automatically recycle Volumes
AutoPrune = yes # Prune expired volumes
Volume Retention = 1 month # one month
LabelFormat = "Vol01"
}
So, just 2 questions : Is my strategy right ? Why are the volumes growing ?
Thanks for any help !
