Backup not working to NFS-Share

pnemenz · January 14, 2020, 9:22pm

Hello all,

NethServer Version: NethServer release 7.6.1810 (final)

Since Jan 10th the Data backup is’nt working anymore. it worked before without any problem for years.

I don’t get any entrys in /var/log/messages. in the backup log there is

Backup: backup-data
Backup started at 2020-01-14 22:12:44
Event pre-backup-data: FAIL
Backup status: FAIL

Log file: /var/log/backup/backup-backup-data-202001142212.log

I don’t find anything else in any logfile.

Is there a something like verbose level for the logs?

Please take a look: daily-backup-error

Thank you for your replay, but this is not working for me. the last backup log is from Aug 2018 and even after deleting the content of the folder /var/lib/nethserver/backup/duplicity/ the backup fails.

federico.ballarini · January 14, 2020, 10:57pm

Could you post /var/log/messages?
The problem is in pre-backup-data.

Please follow this:

grep pre-backup-data /var/log/messages

You should find some lines like these:

Jan 14 03:00:04 mail esmith::event[4239]: Action: /etc/e-smith/events/pre-backup-data/S20nethserver-backup-config-predatabackup SUCCESS [1.65277]
Jan 14 03:00:04 mail esmith::event[4239]: Action: /etc/e-smith/events/pre-backup-data/S50mysql-dump-tables SUCCESS [0.362955]
Jan 14 03:00:04 mail esmith::event[4239]: Action: /etc/e-smith/events/pre-backup-data/S50nethserver-ejabberd-backup SUCCESS [0.297388]
Jan 14 03:00:04 mail esmith::event[4239]: Action: /etc/e-smith/events/pre-backup-data/S50nethserver-webtop5-backup SUCCESS [0.152889]
Jan 14 03:00:04 mail esmith::event[4239]: Event: pre-backup-data SUCCESS

Take the number in parentheses like [4239] and then launch

grep 4239 /var/log/messages

and post the output.

Replace the number with the number in your logs.

pnemenz · January 14, 2020, 11:09pm

nope, there is nothing in there

federico.ballarini · January 14, 2020, 11:10pm

Strange… have you cleaned your logs?

pnemenz · January 14, 2020, 11:10pm

no I hven’t

federico.ballarini · January 14, 2020, 11:11pm

Try launching on CLI signal-event pre-backup-data and then check your logs

pnemenz · January 14, 2020, 11:14pm

still nothing in the logs. I just checkt some older log, when the backup was working, even there was nothing in the log file.

federico.ballarini · January 14, 2020, 11:16pm

I’ve just launched the command on my server and in /var/log/messages I can found some entries…

pnemenz · January 14, 2020, 11:20pm

thats strange.
is the loglevel somewhere to adjust?

federico.ballarini · January 14, 2020, 11:21pm

Post the output of ls -l /etc/e-smith/events/actions/pre-backup-data

pnemenz · January 14, 2020, 11:22pm

federico.ballarini · January 14, 2020, 11:27pm

Ok, you should execute these scripts and check which one has problems (I think mysql-dump-tables).
Try

/etc/e-smith/events/pre-backup-data/S50mysql-dump-tables

and post the output.

pnemenz · January 14, 2020, 11:50pm

thank you verry much. it was a missin right on the database. looks like its working now.

but still strange there are no entrys in the logfile

federico.ballarini · January 14, 2020, 11:51pm

Program your backup and check if next days there are populated logs. I suggest you also to check permissions on /var/log folder.

Please mark this topic as solved. If you need help with logs, I suggest you to open a new one.
