Re: [Bacula-users] why do i need to label this?

Sorry for the last post ... 

I guess I'm missing something now. I've changed my volume retention to 5 days (I run tapes Mon-Fri and have a different pool for the weekend when I'm not around) and bacula still refuses to write over the data. Am I missing something? Doesn't "Volume Retention = 5 days" mean "Keep this volume for 5 days, but after that it's stale and overwrite it."?

I have also ran "update pool". No luck it refuses to overwrite the old volume despite it being over a week old.

Bacula gives me this error:

Please use the "label"  command to create a new Volume for:
    Storage:      tape-storage
    Media type:   DDS-4
    Pool:         camus-weekly-tape-pool


This is no exactly an error.
It simply means that bacula needs more volume space.


Despite me doing a mt -f /dev/st0 weof in my RunBefore script as well as having the following in my Pool:


Erm. No.
Sorry.
I think you misunderstood part of bacula.
First, bacula doesn't know that the tape is cleared with your model. You'd need at least to tell it that a new volume is in the changer.
Second, bacula is not intended to blindly overwrite tapes. It manages the volume use itself.


Pool {
    Name = "camus-weekly-tape-pool"
    Pool Type = Backup
    Recycle = yes
    AutoPrune = yes         Volume Retention = 80 days
    Accept Any Volume = yes
    Maximum Volume Jobs = 1
    Maximum Volume Bytes = 0
    Label Format = "camus-weekly-tape-"
    Maximum Volumes = 5
}  


If you really want to overwrite the tape in the drive - which is something I consider wrong - you should set a very short retention time and let bacula itself decide hat the volume can be overwritten.

Now, I can't help you with automatic labeling etc., but there were some discussions on the list about how to implement a backup scheme like you want it.

I wouldn't try that.

I also have LabelMedia = yes
# Tape drive
Device {
    Name = tape-storage
    Media Type = DDS-4
    Archive Device = /dev/st0
    AutomaticMount = yes;
    AlwaysOpen = yes;
    RemovableMedia = yes;
    RandomAccess = no;
    Close on Poll = yes;
    LabelMedia = yes
}
What the heck am I missing?
