Normally, I love Truecrypt, but there are two specific obstacles for now .

 

#1  It seems, in Linux, Truecrypt can't create a sparse file container
volume.  You're required to allocate the whole volume at creation time.  Are
you guys using Truecrypt in Linux, or would you recommend something else?

 

#2  Regardless of platform, Truecrypt stores the volume in a single file.
They say this provides improved security as compared to a bunch of smaller
files with timestamps that update as they're modified (ala sparsebundle) .
But the sparsebundle approach has one major advantage.  You're able to
simply run incremental backup software on your hard drive, and your
encrypted volume will be correctly backed up as efficiently as possible
(only backing up the various 8M chunks that were modified.) .  Unfortunately
backing up Truecrypt volumes can be difficult, because they're huge, and
non-segmented.  You've got to backup the entire volume every time.

 

Does anybody have any suggestions to solve either of these two problems, or
recommend a different product instead of TrueCrypt?

 

Thanks.
