After a number of updates to Synology, I am now at DSM 3.1-1741 network backup seems to work. So my harsh comments on synology, can now be moderated slightly. I can add that their iTunes share just worked with my MacBookPro, so featurewise it is a nice package.
I followed the instructions on the synology forum to verify that the network backup of an encrypted share could actually be seen on the backup NA:
5) Mount the encrypted data...(enter your passphrase - the one you entered when creating the shared folder on the synology box) (select cipher 1=aes) (select key bytes 2=32) (select enable plaintext passthrough = n) (select enable filename encryption = y) (accept default FNEK Signature by pressing ENTER at prompt) (choose 'yes' when asked if you would like to proceed with the mount) (choose 'no' when asked if you would like to append signature to the cache file) 6) Change to your decrypted mount point to access your data...
- Code: Select all
sudo mount -t ecryptfs /home/steve/@crypttest@ /home/steve/crypttestYou can automate the mount by supplying the interactive choices as command line options, e.g.
- Code: Select all
cd /home/steve/crypttest ls -l(Put in all on one line without the \ characters if you like. I found that this forum system truncated the line, so I've split it up here.) This is assuming a passphrase of 'blahblah'. The signature values for your mount command can be found by typing 'mount' at the command line after your first successful interactive mount. Look for the relevant entry and copy the signature strings from there. You will only have the same signature strings as me (6c6e2b8b7d94ce23) if you choose 'blahblah' as your passphrase! Hope this helps someone. I spent ages trying to get this working on older versions of linux. It's not worth the pain, in my opinion. But you will need CONFIG_KEYS enabled in your kernel build if you go down that route. Steve

I probably have too many files to sync, so I am trying to increment a number in a conf file as adviced here in the synology forum:
