Compressing data written to Truecrypt container by rsync

Question

I want to rsync data into a Truecrypt container. However, since the data consists of highly compressable files (text), I'd like to compress everything on the fly too, while the files are being written to the Truecrypt volume. Filesystems are ext4.
How would I do the "transparent compression" thingy?

Answer 1

You have two different options; compress each file individually, or create a single file from all files and compress that. The first variant allows you to access single files, but takes more space. The second variant results in better compression but you need to uncompress everything to access a single file. Using rsync is only possible with the first variant, as rsync deals with individual files.
