Amanda backup - Strange Dump Details

Hello!

I’m running the latest openhabian on Buster on a Raspberry Pi 4 Model B Rev 1.1. I’ve tried to setup Amanda backups on to a NAS via NFS.

I’ve read through the docs and did the first backup.

This reports me now:

STRANGE DUMP DETAILS:
  /-- openhab /var/lib/openhab2 lev 0 STRANGE

Complete one is:

Hostname: openhab
Org     : openHABian openhab-dir

These dumps were to tape openHABian-openhab-dir-001.
The next 10 tapes Amanda expects to use are: 10 new tapes.

Did I do something wrong? The system is absolutely standard. Nothing got installed except stuff available in openhabian-config.

ZRAM enabled ?

Edit /etc/amanda/openhab-dir/disklist and create a separate line for persistence.

See https://serverfault.com/questions/915726/difference-between-amgtar-and-gnutar and edit the dumptype in amanda.conf if you want to get rid of the message.

Yes. ZRAM is enabled.

Mmmh which additional directory should go in the disk list?

/var/lib/openhab2/persistence

@mstormi

Thank you very much.

I have changed now the disklist.

Is the change of the dumptype something required or just optional to get rid of the message?

Ok I think I got now a bigger problem. :frowning:

The amdump openhab-dir failed while backing up the whole sd card (16GB). I had to restart the pi to gain access again. After removing the sd card from the disklist and trying to do another backup I’m getting the check result above.

A simple test of sendmail results in:

Have you got any idea what could have gone wrong?

Seems Amanda cannot write to /var/log. Possibly ZRAM didnt sync when you powercycled. Restart ZRAM and or create/set permissions on those dirs it complains about

Yeah that seemed to be the reason for the error. The system is working now fine again.
