I have several files that I need to keep encrypted on my home hard disk.
I currently use a TrueCrypt file container, currently around 100MB in size. I need to backup this file daily, and I'm looking for an incremental backup solution.
I read that on encrypted volumes even a small change in a file would change the whole volume and prevent the use of an efficient incremental backup solution. Any ideas how to backup in this case in an efficient way which would allow incremental solution?
I currently use TrueCrypt as my backup solution and CrashPlan as my backup utility, but I'm willing to experiment with alternatives.
What operating system? – Robert – 2011-07-08T18:01:40.177
Could you do an incremental backup into another container? So if you have 7 containers, Mon, Tues, Wed, Thurs, Fri, Sat, Sun then you can mount the appropriate drive each day to drive X. Use SyncBACK or similar to do an incremental backup to these containers. That way you have a rolling 7 day backup. It's just like having a Tape Back Up but encrypted and all digital. – kobaltz – 2011-07-08T18:04:25.590
Robert, the OS is Currently windows. kobaltz, I'm using an automated backup solution (If I had to trust myself, I would backup for a week and then forget about it. – Mosh – 2011-07-08T19:11:57.977
Robert, as I mentioned below, adding a 14 bytes file ("hello world" of course) changes 22K bytes in the container. Adding a 1MB word file sends my diff application to 100% CPU hell, so I guess the change is a major one. – Mosh – 2011-07-08T19:20:51.210
Gareth, can you help me edit some other stuff? I'm writing an introduction for an article and I can use some help. ;) – Mosh – 2011-07-09T06:19:32.467
