I would like to echo this question... not sure why both of those steps
would be needed. My guess is because either of them might be on or off
(AutoPrune and Prune Oldest Volume).

I agree with you about moving 8 before 7.
But from my test, I think that 8 is currently between 3 and 4.
There is something I don't understand : Is there something the 9 can
do that the 4 couldn't ?
(ie : prune oldest is included in prune all, no ?)

This is maybe more readable :
Yes, thanks, it keeps it all on one line.
So, thanks for the example, this seems pretty clear.
Here is the algorithm that Bacula uses to get the next volume (as
written in the manual):
1. Search the Pool for a Volume with VolStatus=Append (if there is more
than one, the Volume with the oldest date last written is chosen. If
two have the same date then the one with the lowest MediaId is
chosen).
2. Search the Pool for a Volume with VolStatus=Recycle and the InChanger
flag is set true (if there is more than one, the Volume with the
oldest
date last written is chosen. If two have the same date then the one
with the lowest MediaId is chosen).
3. Try recycling any purged Volumes.
4. Prune volumes applying Volume retention period (Volumes with
VolStatus Full, Used, or Append are pruned). 5. Search the Pool
for a Volume with VolStatus=Purged 6. If InChanger was set, go back
to the first step above, but
this second time, ignore the InChanger flag in step 2.
7. Attempt to create a new Volume if automatic labeling enabled If
Python is enabled, a Python NewVolume even is generated before
the Label Format check is used.
8. If a Pool named "Scratch" exists, search for a Volume and if found
move it to the current Pool for the Job and use it.
9. Prune the oldest Volume if RecycleOldestVolume=yes (the Volume
with the
oldest LastWritten date and VolStatus equal to Full, Recycle,
Purged, Used,
or Append is chosen). This record ensures that all retention
periods are
properly respected. 10. Purge the oldest Volume if
PurgeOldestVolume=yes (the Volume with the
oldest LastWritten date and VolStatus equal to Full, Recycle,
Purged,
Used, or Append is chosen). We strongly recommend against the
use of PurgeOldestVolume as it can quite easily lead to loss of
current backup
data.
Please look it over carefully, but it seems to me that if I move item
8 before item 7 (i.e. exchange the two), Bacula will do what you
want. I agree this would be much more logical ...
Please let me know what you think.
I have a pool with two full tapes :
Tape_1|Full|1 week|Recycle=yes|LastWritten=5/11/2005
Tape_2|Full|1 week|Recycle=yes|LastWritten=23/11/2005
And a Scratch Pool with Tape_3.
If I run a job, this is what happen :
Tape_1|Full|1 week|Recycle=yes|LastWritten=5/11/2005
Tape_2|Full|1 week|Recycle=yes|LastWritten=23/11/2005
Tape_3|Append|1 year|1Recycle=yes|LastWritten=23/11/2005
I was expecting :
Tape_1|Purged|1 week|Recycle=yes|LastWritten=5/11/2005
Tape_2|Full|1 week|Recycle=yes|LastWritten=23/11/2005
So Bacula don't really need Tape_3 as it can use Tape_1.
Ludovic.
- The retention of the volume added from the Scratch Pool should
be the
retention of its new pool instead of one year.
Yes, this is a good idea. The Volume should take on the retention
period
of the new pool. Noted ...
