Truecrypt command line interface and ms-backup

[darkamulets]

I'm currently running an MS-backup of a few machines (windows 2003) 3 to be exact, and then running a batch file to copy it to an external network hard drive that we take offsite. I'd like to instead create a truecrypt container and copy my backup into this and then have it copied to the external drive.

Right now I'm figuring a scheduled task to run the MS-backup as it is now, then a batch file to mount the container file, copy the backup to it, unmount the drive and lastly copy the container file to the external drive.

I know this isn't the perfect method but it was either a choice between real backup software or 4 new stations for employees. Anyone done anything similar to this or could point me towards something that might already do this costing little to no cash?

I have used TrueCrypt a lot and what you are thinking of is doable but why don't you create that container on the HD you take offsite instead? And how are you thinking of handling the container(s) password? If you want this to be auto-mounted without you doing anything the password should be included in the batch file. Is this acceptable? Alternatively you can use cached passwords or maybe even keyfiles. Please clarify what you need assistance with.

I wouldn't mind including the password in the script as the container is only used to protect the drive while it's out of the office. Keyfiles sounds like an even better idea, I haven't played around w/ truecrypt much but is it possible to just setup key files only instead of password to access a drive?

Yes it is but it is not recommended. If any bit of the first MB of the keyfile is altered or if you lose the keyfile then the container cannot be unlocked.
