USB disconnects during backup

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. After the disk is gone, only a hard-reboot helps. Until that, the disk is not mountable again.
According to SMART, there are no errors, everything seems to be fine.
The node is in a remote DC, so physical inspection is not really possible.
It seems, that the tar solution worked, but rdiff-backup kills the connection.
Any ideas what causes this?
