Posted March 6, 201410 yr Hello all, I inherited a debian squeeze node with a simple LAMP stack installed. The backup 'solution' they set up is a simple USB disk hooked onto the server with a LUKS+ext4 partition. Previously the files were simply tar-d together and copied to the disk, now I use rdiff-backup instead. The problem is, that the disk randomly disconnects during backup.
