Backup size issue #32

Closed ThorEgilGit closed 6 years ago

ThorEgilGit commented 6 years ago

After I migrated from the patters solution Crashplan reported that I had 141TB of data to back up (I have only 9 TB disk space). After some headscratching I found a @docker directory inside my volume1, and after I removed that one from the backup set everything went back to normal.

Anyone with any idea what this directory is doing?

jlesage commented 6 years ago

It's probably the Docker host’s local storage area (https://docs.docker.com/engine/userguide/storagedriver/imagesandcontainers/#container-size-on-disk).

Excluding this folder is the correct thing to do. This should not be part of the backup.

Thanks. I guess there must be some looping symlinks inside the directory, since Crasplan managed to find 141TB of data in there.

Having the same issue, can you please specify where you found the @docker directory ?

ThorEgilGit commented 6 years ago

On my system it is /volume1/@docker

Thanks for getting back on this :-) On my QNAP, I originally included the "/appdata/crashplan-pro/config" folder in the backup, but somewhere in the CrashPlan PRO configuration, there seem to be a looping symbolic link which in my case multiplied the backup size with approx 10-11x. After excluding the /config folder from the backup, CrashPlan PRO show the correct backup size.
