I have a 1 TB external USB drive with 362 GB used. I'd like to do a

compressed in order to save space (i.e. - the number of DVDs/CDs
used). What is a good program to do this with? Or, what is a good
step of different programs to do this with? I'm a home user with
decent knowledge of Debian/Linux, but not a shell programmer.
Depending on your data, compression may or may not be useful. Video
and audio data is usually already optimally compressed.
4.5G on a DVD is also not terribly useful if you want to back up large
amounts of data. BluRay writers are cheap enough these days, and BD-RE
discs are not too expensive. BD-R discs are even cheaper for doing an
archival backup.
You don't say what you are backing up. If it is the data on the
external drive, you may want to consider getting a second drive and
backing up to that. It's a lot easier than manually swapping discs. In
this case, you could try Bacula. It's not too difficult to set up and
quite flexible.
All the folders in my home folder (except "desktop") is a link to a
folder on the backup drive. These are: Backups, Documents, Downloads,
Favorites, Memos, Music, MyPDA, Pictures, Programs, Projects, Public,
Temp, Templates, Themes, Utilities & Videos. Also, I have the entire
filesystem for this computer and for a separate Windows 7 computer
copied in tar.gz format. (I connect the drive directly to the Windows
box via the usb cable to do that.) There is also a separate "Backup"
folder on the backup drive where I have a couple of programs running
backups /home, /opt & /var and where I also back up cells phones for
friends and relatives (8 at the moment) and things like my camera and
Palm PDA SD cards.
(Speaking of tar.gz; what is a good format for compression for this
varied type of info? I've access to about 20 different formats on this box.)
This is the type of stuff I want to make a safe backup of. I've already
lost all the info on the drive once several months back when someone
defragged it when it was hooked up to the windows box. I have a ton of
old CDs collected from about 10 years of use that I was able to (with a
lot of pain and work) get quite a bit of data back from.
The suggestion of a blue ray drive and disk or a secondary drive sound
like a good one.
Any other suggestions for things I haven't thought of?
