Hi Jon
For example in your AI you should have a full/consolidate pool with is the
target of where incremental are stored.
You extend that pool with next pool -> pointing to your tapes archives pool
(that one need to have its storage definition)
Here is how I use it @home to export once a month my ai_jobs
ai consoliated pool
Pool {
Name = "ai_consolidated"
Description = "AI consolidated"
ActionOnPurge = Truncate
MaximumVolumes = 48
MaximumVolumeJobs = 8
VolumeRetention = 3 months
VolumeUseDuration = 23 hours
* NextPool = "vf_archives"*
Storage = "ai_storage"
RecyclePool = "scratch-ai"
ScratchPool = "scratch-ai"
FileRetention = 3 months
JobRetention = 3 months
}
*show pool=vf_archives
Pool {
Name = "vf_archives"
Description = "VF Archives Virtual Fulls"
LabelFormat = "vf_archives-"
MaximumVolumes = 16
MaximumVolumeBytes = 1 t 776 g
VolumeRetention = 3 months 2 weeks 1 days
VolumeUseDuration = 1 days
*Storage = "vf_archives"*
FileRetention = 4 months
JobRetention = 4 months
}
One of my VF job looks like
*show job=vf_month
Job {
Name = "vf_month"
Type = Backup
Level = VirtualFull
Messages = "standard"
Pool = "ai_consolidated"
VirtualFullBackupPool = "vf_archives"
Client = "client-fd"
FileSet = "fileset"
Schedule = "vf_archives_month"
JobDefs = "default_jobdef"
Priority = 12
RunScript {
Console = "update jobid=%i jobtype=A"
RunsWhen = "after"
}
Accurate = Yes
AllowDuplicateJobs = No
CancelLowerLevelDuplicates = Yes
CancelQueuedDuplicates = Yes
}
Which is scheduled by a normal schedule first sunday at 3am.
Hope this will help you to glue the last bytes of your configuration.
