Backup Central

Hi there everybody,

I'm trying to define sets for the following backup policy:

- 12 tapes: one for each start of month
- 5 tapes: one for each end of week (Friday)
- 4 tapes: Monday to Thursday.

I've defined three diferent configs, Monthly, Weekly and Daily. W and D
are working without a problem, but Monthly is generally done some day
between Monday and Friday.
I get the following report whith 0 bytes backed up, I suspect it has
something to do with Daily or Weekly having been run the same day.

Any help will be gratly appreciated.

--------------------------------------------------------------------

The dumps were flushed to tape Monthly-1.
The next tape Amanda expects to use is: a new tape.

The dumps were flushed to tape Monthly-1.

Are you running amflush instead of amdump?
What does your amanda,conf for this config look like?
Even if this output was the result of autoflush being set I still
think you would get some output about not doing the dumps.
What does amcheck on this config return?

Two things to watch out for:

1. I believe amanda _really_ doesn't like running more than
once per day. At least in a single config. Having multiple
configs _might_ avoid her objections there though.

2. Make sure your incrementals are doing what you expect.
In particular, the "listed-incremental" files will be
shared between configs. Meaning the level 1 on that
weekly tape is relative to the level 0 on the daily
that came before it, for instance....

I posted about #2 some months ago, and suggested that I might
come up with a fix for it. Unfortunately I never did; we ended
up rearranging things rather creatively to get around the
problem here.

I've heard that a few times before, but I still don't quite understand
what the problems are supposed to be. I actually *did* two runs the
same day not long ago, and I haven't observed anything out of the
ordinary so far. What should I be looking out for?

Thanks,
Alex

It does work when running many times a day.

The problem areas are: you

Amanda can run many times a day.
In my test set up, I do it frequently.
Also, when some important DLE failed, I sometimes do run a
'amdump daily veryimportanthost /Very/Important/Disk' on the
same day manually.

Problem area's are:
- holdingdisk: if you run into degraded mode because there was
no tape in the drive, you overwrite the files in holdingdisk
- amrecover works by datestamps, not datetimestamps. Also the info
database with information about which tape contains what had only
datestamps. You can always use amrestore instead of course.
- you will never get a level 0 dump except the first run that day,
unless you specify dumpcycle 0 (that's not a bug; that's expected
behaviour)

(That's what I can think of now, maybe there are more issues.)
