I'm running C5.8 and want to backup a directory that is 6GB in size.
Is there any Linux program for Centos to make this backup over 2 x 4.4GB DVD+R disks please?
Something with a GUI like K3b would do nicely.
Kind Regards,
Keith

OK I have found dar in EPEL
http://en.wikipedia.org/wiki/DAR_%28Disk_Archiver%29
and a gui for it called dargui
http://dargui.sourceforge.net/
I have downloaded the 0.7.0 linux version, and run the ./install.sh script, and it has installed itself on Centos 5.8 32bit and runs nicely.
What would be handy is to be able to make my overnight directory backups into slices, so they are ready to burn to DVD's whenever I want to.
Kind Regards,
Keith

Assuming you have space to hold the temp copies, why don't you do something like: tar -czf - dir |split --bytes=4G /parth/to/prefix
Odds are good that a 6GB dir would compress to fit on on DVD anyway.

Thanks Les.
dar supports slices, and the GUI looks good for it as well.
I might not even bother with compressing things, just want backups to write to DVD's away from the computer.

Just a knee-jerk reaction because I like it so well, but whenever anyone mentions backups I have to recommend backuppc. If you have any other system that can work over the network (perhaps offsite via VPN) and hold copies on-line you might like it. It is the kind of thing that you can set up once and it will take care of itself for years. It can use rsync for the transport so after your initial copy you only need bandwidth for the changes.

That's something I might take a look at. What I want to do is make backups that are on removable media, so they are not dependant on a machine for their data safety. Once I have burnt the backups to DVD they will be stored away then, just in case I need them.

Backuppc has an option to do something like that out of the backup copies (extract the equivalent of a tar, compressed and split to files that will fit on your backup media) but it is sort of an afterthought. The real focus is on keeping a history of backups online stored in a very efficient form so you can keep much more than you would expect online and available in a given amount of disk space. It is much easier to use its web interface to pick a file from last month to restore than to have to extract it from some huge old tar files on dvds.

Thanks for your helpful replies Les and others.
I've dealt with the directory size issues by using
$ du -sch DirName
to give a listing for the size of all the subdirectories and files in DirName directory.
To split the files under DirName i created 2 subdirs called
xxx_DVD-1 xxx_DVD-2
and just moved stuff to each subdirectory using F6 key in mc. Then ran du -sch on each of the DVD-1 and DVD-2 sub dirs.
I don't really want to compress things anyway. So that's the file and directory sizes sorted.
My only problem now is because some files were created on different OS's, such as Win 32 and possibly Mac OS(X) K3b complains that the character set encoding for the filenames is wrong, and will not create the iso image for me.
So I done some Googling and found this posting:
International Chars cause backup problems http://forums.fedoraforum.org/archive/index.php/t-98363.html
Then I installed convmv and read the docs on that.
I'm still not sure how to identify out of 4.3G what character encodings are used for certain files.
Is there any way to grep for a listing of these character encodings, so I can tell convmv what sets I want to convert into utf8 please?
Kind Regards,
Keith Roberts

i suggest to burn it twice on different media and migrate the data to new media after a couple of years :-)

Hi Leon.
I don't expect to keep the same DVD backup set for more than ~12 months. I just make periodic backups from my dedicated backup drive to DVD/CDs, to get the data away from the PC and onto something hopefully more permanent than HDD's.
Usually I can restore straight from the backup drive in the PC. I may have used the CD/DVD media when 3 HDD's decided to fail at around the same time.
Here's the script's I wrote in PHP to be run by cron in the early hours of the morning, and posted on the Fedora forum.
Generic PHP CL backup script http://forums.fedoraforum.org/showthread.php?t=248436
Kind Regards,
Keith (CD-RW)

From personal experience, I wouldn't qualify burnt DVDs as
"more permanent than HDDs". Chances are high that when your three HDDs do fail, you'll find the DVD you burnt six months ago to be unreadable too. A bag of small inexpensive USB sticks to cycle through is probably more reliable and would free you from the need to split your backups.

Thanks Tilman.
Is it possible your media was to blame?

OK I have found dar in EPEL
I used afio for a "simple" backup script... It can split, it compresses file by file so better recovery after an error...

That sounds OK to me John.
I'll take a look at that sometime soon.
might be able to incorporate afio or dar into my generic PHP backup scripts.
