If you have physical access to a server that contains the encrypted
disk and the encryption key as well, you can still use the key to open
the disk. How could I solve that?

What we are thinking about is something like this (it's a snippit of a
larger script):

/usr/bin/openssl enc -d -aes-256-cbc -in $1 -out "$BESTAND" -pass file:$PAD/$KEY

This command will create a local copy of the repository, which will
then be rsynced to the remote server*.

I wonder if when I execute this command to the files of a SVN
repository and direct the output to another directory, if the new
directory, when restored (decrypted again) would still be a good
useable repo. I guess we have to do some testing.

Has anybody tried something like this?

 *(this sync would function only as some kind of last resort backup)

Thank you for your reply!
