nssbackup

no backup is performed

Bug #330651 reported by Lubomír Sedlář on 2009-02-17

Affects		Status	Importance	Assigned to	Milestone

Bug Description

When I run backup, NSsbackup never finishes it. It pops up a notification about the backup sessions starting and then that it started to commit files to disk. Then it starts to use 100 % of CPU and the directory with the backup is created, except the files.tar.bz2 size is 0 and does not change.

I have tried using gzip or not to compress the backup, but it didn't help. I backup on another hard disk in the same computer, it's mounted in /mnt.

I use Debian unstable and NSsbackup version 0.2-0 RC3 (this is written in Help > About) installed from PPA. I have attached a log file NSsbackup creates with level DEBUG.

Hey Lubomír,

I've looked at your log and couldn't find any suspicous output. But please keep in mind: The creation of a full backup of 13GB (in your case) may take some time. And I mean possibly more than 1 hour. This is because NSsbackup runs at nice level 19 to avoid blocking your system. To prove if this is really a hidden bug I suggest the following: configure NSsbackup to perfom a small test backup (some files) and post whether this works for you.

Moreover read the FAQs related to debugging NSsbackup.

(Unsupported hint: you can renice the priority of the spawned backup process to increase speed)

Please post your results.

I have tried the small test backup and it worked, and with changing the priority, the complete /home directory backup worked too. Is there a way I can force NSsbackup not to change nice to 19?
Anyway, I am sorry for disturbing you with this false bug.

At the moment there is no way provided to change the priority. For later release this is a reasonable feature. I've registered a blueprint concerning this topic (https://blueprints.launchpad.net/nssbackup/+spec/change-priority-of-process). If you want write down some ideas how such feature should work for you and e.g. could be integrated into the GUI.

Thank you.
