The backup configuration is using a CIFS share:

I see here that NFS is more recommended.
I don’t remember if NFS fails for me the first time that I try instead of CIFS; I’ll try to use a NFS share. (and post my finds laters).

If the backup log doesn’t explain why this is, the system log (/var/log/messages) should. Try grep -C 20 pre-backup-data /var/log/messages and see what it tells you.

Thank you, maybe something is broken after the upgrade in (samba); I will try to use the NFS instead (need to find time to do it… now! :fire: :fire_extinguisher:)

Hi,

Quite sure you’re trying to mount and old protocol (1.0) CIFS share from Nethserver.

You need to specify -o vers=1.0 in backup mount script:

/etc/e-smith/events/actions/mount-cifs

Correct Line:

$err = qx(/bin/mount -t cifs “//$smbhost/$smbshare” $mntdir -o vers=1.0,credentials=$tmp,nounix 2>&1);

King Regards

Backup fails because of mount error
#5

Thank you!, It was working before the upgrade, maybe the NAS has the shared folder using the old SMB v1.0 protocol

This is a Synology NAS, and the services is configured as:
image

Right now I put the same share as a NFS.

I wonder how can I force test a backup from the GUI or Terminal?

Honestly I do not know , but you could try scheduling backup job now+1 min and see what happens.

Reading the Backup documentation.
I run this and it doesn’t show anything; is that correct?

# db backups show
#

BTW, I modified the maximum protocol in the nas/synology to use SMB3.
Hoping it fix the issue.

Same behaviour for me.

# db backups show

do not display anything on cli.

#10

Including the same error message? Then try the same troubleshooting steps already recommended up-thread.

#11

It’s normal. “backups” database is for multiple backups feature (available from command line, not from server-manager), and you’ve single backup configuration which can be seen using this command:

config show backup-data

same issue here!
I don’t understand, why there is only "IOError: " and no explanation after the colon…

#15

No errors in /var/log/messages ?
cc @giacomo @Tyno

#16

It’s the duplicity output, maybe something is not currently mounted?

There is no simple way to debug it if duplicity doesn’t show the output …

#17

no nothing to see here

#18

the drive is mounted.
I configured the backup from the cockpit UI and disabled the backup in the old UI, maybe that’s an issue?
Also things worked for some weeks and then it suddenly started…

#19

So it seems more an error on the destination side.

Could you try to change the protocol? Maybe from SMB to NFS?

#20

the strange thing is, that it’s an USB. I formatted it with ext3
according tothe nethserver-manual…
