hi,
we are using bacula to backup our fileserver to disk. Our bacula server 
has got 500GB disk space and we want the backup to work like this:

every 1st saturday of a month at 20:00 start a full backup and overwrite 
the last one (not enough diskspace to hold 2 full backups)
every monday - friday start a incremental backup at 22:00

our schedule looks like this:
Schedule {
 Name = "monthly_disk_inc"
 Run = Level=Full IncrementalPool=sdb1_inc FullPool=sdb1_full 1st sat at 
20:00
 Run = Level=Incremental IncrementalPool=sdb1_inc FullPool=sdb1_full 
mon-fri at 22:00
}


our job like this:
Job {
 Name = "zeus_disk"
 Type = Backup
 Level = Incremental
 Client = zeus-fd
 FileSet = "zeus_disk"
 Schedule = "monthly_disk_inc"
 Storage = sdb1
 Messages = Standard
 Pool = sdb1_inc
 Full Backup Pool = sdb1_full
 Incremental Backup Pool = sdb1_inc
 Differential Backup Pool = sdb1_diff
 Priority = 9
 Write Bootstrap = "/var/bacula/zeus_disk.bsr"
}


and our pool like this:
Pool {
 Name = sdb1
 Storage = sdb1
 Pool Type = Backup
 Recycle = yes                       # Bacula can automatically recycle 
Volumes
 AutoPrune = yes                     # Prune expired volumes
 Volume Retention = 14 days
 Label Format = "file-"
 Maximum Volume Jobs = 1
 Maximum Volumes = 3
}


## sdb1 full backup pool
Pool {
 Name = sdb1_full
 Storage = sdb1
 Pool Type = Backup
 Recycle = yes                       # Bacula can automatically recycle 
Volumes
 AutoPrune = yes                     # Prune expired volumes
 Volume Retention = 1 month
 Label Format = "full-"
 Maximum Volume Jobs = 1
 Maximum Volumes = 1
}


## sdb1 differential backup pool
Pool {
 Name = sdb1_diff
 Storage = sdb1
 Pool Type = Backup
 Recycle = yes                       # Bacula can automatically recycle 
Volumes
 AutoPrune = yes                     # Prune expired volumes
 Volume Retention = 1 month
 Label Format = "diff-"
 Maximum Volume Jobs = 1
 Maximum Volumes = 12
}

## sdb1 incremental backup pool
Pool {
 Name = sdb1_inc
 Storage = sdb1
 Pool Type = Backup
 Recycle = yes                       # Bacula can automatically recycle 
Volumes
 AutoPrune = yes                     # Prune expired volumes
 Volume Retention = 1 month
 Label Format = "inc-"
 Maximum Volume Jobs = 1
 Maximum Volumes = 31
}

Differential is not used at the moment. Will this setup work? What 
happens if I start at 13.November.2007? Will Bacula start with a full 
backup an overwrite the fullbackup "tape" at 1st saturday on december? 
Will it also overwrite the incremental tapes that are no more working 
because of the deleted full backup? Are the Retention times ok?

Thanks for you help.
