Hello,
I'm running Linux Debian with Bacula 1.36.3 and sqlite.
I have two clients (canis and bebif) to backup, three pools: one for
full backup (for both client), and two for incremental backups (one for
each client).
(In fact I have more clients, but those are not problematic because I do
only a full backup of them once a week)
I do:
- FULL backup of CANIS every monday at 3:00 AM
- FULL backup of BEBIF every tuesday at 3:00 AM
- INCREMENTAL backup of BEBIF and CANIS every day at 20:00 PM
Here is the Pools definition:
########
# P O O L #
########
# FULL
Pool {
Name = tape-pool-full
PoolType = Backup
LabelFormat = "Full-"
Recycle = yes
RecycleOldestVolume = yes
MaximumVolumes = 18
MaximumVolumeJobs = 0
VolumeUseDuration = 0
VolumeRetention = 30 days
CatalogFiles = yes
AutoPrune = yes
AcceptAnyVolume = no
}
# INCREMENTAL
Pool {
Name = bebif-pool-incremental
PoolType = Backup
LabelFormat = "Bebif-Incremental-"
Recycle = yes
RecycleOldestVolume = yes
MaximumVolumes = 15
MaximumVolumeJobs = 1
VolumeUseDuration = 0
VolumeRetention = 10 days
CatalogFiles = yes
AutoPrune = yes
AcceptAnyVolume = no
}
Pool {
Name = canis-pool-incremental
PoolType = Backup
LabelFormat = "Canis-Incremental-"
Recycle = yes
RecycleOldestVolume = yes
MaximumVolumes = 15
MaximumVolumeJobs = 1
VolumeUseDuration = 0
VolumeRetention = 10 days
CatalogFiles = yes
AutoPrune = yes
AcceptAnyVolume = no
}
Everything works fine, except that sometimes an incremental backup is
upgraded to a full backup without any reasons.
Here is the list jobs output (I hope it will be readable) :

As you can see, we are today 2006-01-09. A full backup on tape of client
canis started at 3:00:02 and finished successfully (job id 65) at 08:51.
Why on 2006-01-09 at 20:00 PM the incremental backup is upgraded to a
full backup (job id 66) ?
As you can see, job id 62 has also been upgraded to a full backup
without any reasons because job id 53 was a full backup three days ago
... I'm a bit confused ...
Any ideas ?
In advance thanks for support,
Julien
