Is there such a thing as a file hosted container which deduplicates data held within?
- by Mallow
Background
I have backups of a website which stores all of it's data into a single file. This file is several gigs large and I have many different backups of this file. Most of the data within is mostly the same plus whatever was added or changed to it.
I want to keep all the concurrent backups I've made through the years in case I find a horrible surprise of data corruption along the line. However storing a 10gig file every month gets expensive.
Seeking Solution
I've often thought about different ways of alleviating this problem. One thought that comes up very often combines the idea of a duplicating file system which doesn't require it's own partitioned volume on a hard drive. Something like what truecrypt does, what it calls, "file hosted containers" which when using the truecrypt program allows you to mount and dismount that volume as a regular hard drive.
Question
Is there a virtual hard drive mounter which uses file-based container which uses data deduplicaiton file system?
(This question is a little awkward to put into words, if you have a better idea on how to ask this question please feel free to help out.)
