Hi,
I had a very simple setup for the last 12 months.
* backup everything to tape and keep the last 2 weeks before
recycling old volumes
* keep the monthly tape(s) for 3 years
I didn't care much about the retention periods of the monthly tapes. I
just set the Volume Retention to 3 years for the 3-year-pool and 16 days for
the regular backup.
In the Job resource I chose a file retention period of 30 days and a
job retention period of 6 months.
File Retention = 30 days
Job Retention = 6 month
With our new LTO3 40x lib we want to keep more backups and put some
tapes with selected data/files in the safe forever (at least until our IT
department can offer us more than just a 60 days period...).
New setup:
* daily inc. backup (keep 14 days)
* weekly diff. backup (keep 4 weeks)
* monthly fill backup (keep 6 months)
* full backup of certain directories 3x year (keep forever)
Schedule {
Name = "Regular Backup"
Run = Level=Full Pool=Full 1st sun at 0:05
Run = Level=Differential Pool=Differential FullPool=Full 2nd-5th sun at 0:05
Run = Level=Incremental Pool=Incremental DifferentialPool=Differential
FullPool=Full mon-fri at 0:05
}
# archive, only 3x year
Schedule {
Name = "Archiv"
Run = Level=Full Pool=Archiv 1st sat jan,may,sep at 6:00
}
I created differnt pools for regular backups and long term archival. I think
the retention times are reasonable. We are aware that we can't handle a _real_
long time archival (copy to new media, verify...), but we want to keep the
volumes for 30 years.
Pool {
Name = Archiv
Pool Type = Backup
Recycle = no
AutoPrune = no
Volume Retention = 30 years
}
Pool {
Name = Full
Pool Type = Backup
Recycle = yes
AutoPrune = yes
Recycle Oldest Volume = yes
Volume Use Duration = 96 hours
Volume Retention = 180 days
}
Pool {
Name = Differential
Pool Type = Backup
Recycle = yes
AutoPrune = yes
Recycle Oldest Volume = yes
Volume Use Duration = 96 hours
Volume Retention = 31 days
}
Pool {
Name = Incremental
Pool Type = Backup
Recycle = yes
AutoPrune = yes
Recycle Oldest Volume = yes
Volume Use Duration = 6 days
Volume Retention = 14 days
}
So far so good. But I'm bit unsure about the "right" File and Job Retention
periods. I can set these times only in the client resource, but I would like to
differ the period if the job is a regular backup or an long term archival job.
For the regular backup I would choose 6 months for File/Job Retention, because
that's the longest period until a tape will be recycled again (full monthly
tape). For the archival job I would like to keep the file/job information
longer, not 30 years, but maybe 5 years for the file records.
How can I accomplish this? Any thoughts about this setup or configuration?
Thanks, Ralf
