Eversince upgrading to 8-series from 7, the automatic backups won't run. The scheduled backups die with the following log entry:

[03/Jul/2013 01:00:00] backup.cpp: BACKUP: Can't open file /mnt/backup/F20130702T220000Z.part.
[04/Jul/2013 01:00:05] OZipFile.cpp: BACKUP: Insufficient space on backup disk (871 MB), minimal free disk space required for backup is 2560 MB.


The disk space shouldn't be the issue, the mount point has over 850 gigabytes of free space:

Filesystem                  Size  Used Avail Use% Mounted on
//xxx/keriobackup/          5.4T  4.6T  867G  85% /mnt/backup


Starting the backup manually from the WEB GUI works and creates a backup as expected, so there's no any permission issues or similar on the OS level.

Searching the forums gave me a hit on similar issue with an older 7-series Connect. We're currently running 8.0.2, but couldn't spot any backup-related fixes in the changelogs of newer releases.

Sorry for the "me, too". I'm having the same issue since upgrading to 8.1.1. Incremental backups are fine, but the weekly Full backup fails. Plenty of disk space on the target backup disk. From the error, it looks like Connect may be trying to make the zip on the disk that contains the mail store (which is in need of an upgrade and cannot accommodate double the mail store) although I didn't run anything to confirm that.

Hi, Guys

This is a strange one...


ASovijarvi - If you do a du on all your drives, do you have one that has only 871Mb free?

I think that this may be worth while raising as a full support ticket, since we have not come across this particular problem before. http:/www.kerio.com/support

There was no drive with that amount of free space; the first thought was that something was left unmounted, but even the root partition has over 10 gigabytes.

The mysterious thing is, that this problem disappeared after we upgraded to 8.1.2; the backups run again normally.

I have same problem sometimes and noticed this when rebooting Connect from console this error occurs and when booting Linux mount starts working normally again and backups are fully working with right mounting point. So login to Linux as root and reboot host Linux.
