When Kerio Connect backup does not find the drive it's looking for a folder might get made at /Volumes For example /Volumes/backupHD
When the drive then tries to mount it gets moved to /Volumes/backupHD 1 The backups keep going to the folder that got created. That folder is always on the boot drive.
The boot drive fills up and then the server goes down. Or worse, it stays up and provides slow response while it corrupts dozens of random files, including the fresh backups.
This old thread http://forums.kerio.com/t/19141// shows that the problem has been around for a while. I had Kerio 8.2.2 on a Mac server running 10.6.8 but there is a report of another OS having the same problem. This happened a few months ago so I updated everything and ordered a new server. It happened again before I got the new server installed. I am kicking myself over that one!
I called tech support to figure out the best strategy to merge the week old good backup with current data from the crippled server. They blamed Apple as the source of the problem. I think he called it the virtual folders problem.
To mitigate this I suggest that your boot drive be WAY oversized and your mail store be on a different drive. That means that you probably can't go for a high performance SSD boot drive. Also adding an email alert for that drive getting full would be a good idea. My client wants to move their mail service to the cloud now.
Also the /Volumes folder is hidden and only accessible by root. So it took me a while the first time to find where all my drive space had gone.
If this happens rarely, then I guess I am just unlucky. If it is common, then I think Kerio needs to fix it. I don't know if this is a bug fix or a feature request. Chime in if you have seen this problem.
Seen it for years and still have problems with it.
Why would Kerio Connect EVER need to create something in the /Volumes directory?
We even have a script running on the server looking for a special file ".thisIsAMountedVolume" and taking actions when not seeing it.
PS. CrashPlanPro Server has the same behavior.
