Hi,
I have a Windows XP computer with an 80GB hard drive.
The documents and other files that I need to backup take about 20GB.
I can't remember if that's compressed or uncompressed - I just tend
to zip or .tar.gz them up.
If possible I'd like to have at least my documents automatically
mirrored during the day onto (at least) one external hard drive.
If the cost isn't too prohibitive, perhaps the whole 80GB hard
drive could be mirrored.
Preferably, I'd also like to be able to do incremental backups
during weekdays (i.e. backup only those files that changed "today").
If I had Linux installed, the 'find' command could easily do incremental
backups at least. But on XP I tried using DJGPP to simulate Unix
commands like these, and I found trying to do things like
find .... | xargs ....
was just too flaky, constantly giving errors.
I'm probably looking for some sort of 'simple' commercial or
open source solution. I know that what I'm asking for (mirroring including
incremental backups of a single hard disk) is not very hard and is
standard, but I just haven't studied backup techniques before.
I hope that I can find something that's fairly low cost.
P.S. Preferably, I would also be able to either password-protect or
encrypt the external hard drive, or the individual files within it.
Something like GPG can very securely encrypt individual files, but
the way it renames the files (to .gpg and deleting the prefix) seems
like it can be hard to restore them to their individual names
(I could be wrong though some someone please set me straight if so).
Thanks very much for any advice that you can provide to me!
