rsync and truecrypt
Just for any others searching here for the wealth of knowledge
In reference to the posts from 2007 below, you may want to look into the "timestamp" aspect of the container mount options. This will probably avoid having to use --checksum

backing up truecrypt drive with rsync
I've had rsync setup correctly for ages to backup my /home to an external disk, but I recently started using truecrypt to create an encrpyted file which I then mount as a drive (so its not a hidden volume in truecrypt)
problem is that rsync doesn't seem to notice that the encrypted file (containing my encrypted directory) has changed, so it doesn't update it. .... i'm assuming this is because of the security of truecypt that it doesn't show when the file was last modified.
any ideas how to overcome this?
maybe id just have to manually specify it to write that file each time?

Re: backing up truecrypt drive with rsync
doesn't matter... found the answer (after looking for F***ing ages, make a post, then i stumble accross it, typical!)
for anyone else looking at this, ..
you need to use the --checksum option (-c flag) takes a LOT longer, but needed to termine if the truecrypt volume has changed.. so prob better to have 2 rsync commands, one which does the main drive, then one which does the folder containing truecrypt drives.
Re: rsync and truecrypt
The encrypted file time and size never changes. Therefore you need to omit the -u (update) option when using rsync on these type of files.
