Systemdisk getting full after making a USB-Backup...

FFrank · 31. Januar 2019

Hi,
I have a strange problem.
I configured the USB backup plug-in to backup my whole data disks. I did the first backup - all seemed to run ok (I am just wondering how I see if the process is done).

But after/during the backup my system disk was running full. I was afraid that it will run into problem when totally full so I rebooted the system. Now the system drive is more than double the size than before (see picture)...what happened? How can I check/delete this?

Any help greatly appreciated.
Thanks.
Best.
Fabian

It may be that you have specified a wrong destination. Did you connect an external USB drive to your OMV NAS? Was the backup written to this disk? Or accidentally to the system drive?

FFrank · 31. Januar 2019

I attached an external USB drive - it was new. I deleted it and created an filesystem (ext4). After this I enabled the USB-Backup Plugin.
The destination was correct. The external drive was getting full. I just checked: the data is there...
?!? Strange.
Any Idea?
Thanks.

In which folder could I find some data?!? I am lost...quite new to linux and not very familiar with the folder structure in a Linux-box.

Take a look in /tmp
This should be, mostly, empty.
(What's there might be the text of dialog warnings from past operations, at 1 or 2K per file, and a few hidden empty folders.)

I've seen some app's/utilities use this location when moving files. In the instances I've noticed, it cleans up after the operation is complete.

Otherwise try the following on the command line:

du -d1 -h /

This shows the amount of data, in all folders, at the root /*

OK, thanks.
TMP is almost empty.

Here is the output of your command...I wander that I only get 3 folder...should I wait longer?
I did not get a prompt again?!?

Thanks for your help!

I just got in idea.
I have some Backups of my systemdrive via the backup plug-in. Is there a way to mount the fsa-file and compare with the systemdrive...it should be easy to find all this extra data...
???

I don't use the plugin, so I have no idea. I use USB boot drives and clone them. (Restoration takes 2 or 3 minutes.)

Yes, it might take awhile. When it's done, the prompt will come back.

Ignore results under /srv . This is where your data drive(s) are mounted.

You must be in the EU.

Here's a sample output from my server. (16GB USB)

(I deleted similar process errors, there were several. Ignore.)

Great, I will compare.
Strangly enough the systemdisk is almost back to normal...I started a new USB-Backup over night. And now I am at 14GB - still a lot, but way better than before...So maybe the problem will solve by itself? Maybe the USB-Backup plugin is caching something?
I will report back when I get things clear.
Best.

Not that I know. It uses rsync for the copy job.

(I am just wondering how I see if the process is done).

As I know a buzzer beep is generated when the USB backup job starts and a second beep is generated when the job has ended. Of course it requires a buzzer in hardware.

The plugin mounts the USB drive and unmounts it at the end. If the drive is unmounted this could be a second indicator that the job was already finished.
