Look at dar itself then. kdar is just a front-end. dar isn't very hard to set up.

Look at DAR and KDAR (a front end to dar) It will split files based on your size settings.

Why not use K3b to backup. It uses drag-n-drop.

There is also mondo/mindi that will let you backup to specified media. Last I used it it did not support DVD but I used the CD option and gave it a slice size for a DVD (4.3G) anyway and it worked. Burned the resulting ISO to DVD and was on my way. If you have double-layer DVD's you could back up to one. mondoarchive is used to backup and mondorestore is used to restore files. This also provides disaster recovery if you want to backup everything, it generates a boot restore iso you can burn to CD.

mondo does dvd's now, just use r as a the device option and set the size (option s) to 4700m or 4.7g and it'll burn to dvd (if you have a dl burner, then sizes can be increased). Or, you can have it create isos that you can burn using another utility, say k3b. And the baremetal recovery is nice, just boot the disc and nuke it or do a custom restore. Oh, and the backups can stored on nfs if you have a network available. I'm using it to back up genetics databases and research data on a RHAS box. John

Hi there,

I need to backup data from my /home to DVD. I have around 6 GB of (uncompressed) data. Can somebody recommend an easy to use backup utility?

Should I be aware of a maximum size of tar.gz-files? - Is there e.g. a 2 GB limit?

I don't know of a maximum file size, but tar can span multiple volumes.

Tar does not have a max. filesize. It simply does sequential reads/writes. The filesytem your writing to may, but most Linux filesystems can go past 2 GB. FAT32 has a 2 GB limit, so definately don't use a FAT32 volume as a staging area. Are you having problems? Or just worried? Greg -- Greg Freemyer The Norcross Group Forensics for the 21st Century

Please qualify this statement, Greg. I don't think its entirely accurate. I hate to "nit-pick" but this is the kind of misinformation that one person reads, accepts as gospel, passes it along to family and friends who, in turn, pass it along to their family and friends until it circles the globe a couple of times and ends up back here as a question. And the first one to pick it up and pass it along can have his life ruined, too: - he's made to look foolish in front of his prospective father-in-law, an ill-tempered sysadmin, who then increasingly starts finding fault with him - his girlfriend dumps him from the familial pressure and embarrassment - his hoped-for computer shop never materializes - the disappointment and broken heart lead him to drugs, alcohol, fast cars and women - he eventually dies penniless and homeless, his sole remaining possession being a worn-out CD containing partially corrupted jpegs of his ex-girlfriend from the better times. Sad, isn't it? - Carl ;-)

Carl, I don't know what you mean? As far as I know the FAT 32 filesystem has a 2 GB max file size. Therefore it would be a very bad place to stage tar files larger than 2 GB. If you know otherwise I would be very interested. I really _need_ a reliable and readily available solution for moving large files from Linux to Windows. Right now I always use split to break the files into 2 GB or smaller pieces and write them to FAT32. Then I have the choice of using specialized software that can work with the split images (I'm talking about Computer Forensic software and much of it does support split files.) Or I can re-assemble the pieces via Windows by writing to a NTFS partition. FYI: I am not saying anything about FAT32's max filesystem size. I don't know what it is, but with Linux I have formatted single partitions up to 400GB. The standard Windows OS tools refuse to create that large of a FAT32 partition. Third party tools like partition magic will also format large partitions as FAT32. Greg -- Greg Freemyer The Norcross Group Forensics for the 21st Century

Retract the below.

I just read Christopher Shanahan's mail (thanks for that) that gives further resources that talk about the 2 GB vs. 4 GB max filesize issue.

I will need to experiment with that because I would really like it if I could size up to 4 GB splits of my files.

1) I don't know exactly what the FAT32 max file size is, but it's not 2 or 4 Gb, as I have files larger than 4Gb on a FAT32 volume. 2) If you mentioned what version of SuSE you're using I missed it, but there are a few ways to write directly to an NTFS volume from linux - For SuSE 10 (which has fuse capability without kernel hacking), the ntfsprogs (not included w/ SuSE - google for ntfsprogs-fuse) work for me so far. For most previous versions of SuSE I used captive-ntfs, which works (when it works at all) very well - but the author has orphaned it. If it works with your kernel, you're good to go, but if it doesn't, it won't. I also tried the commercial product "write anywhere" - it's complete crap. Mike- -- Mornings: Evolution in action.

Interesting, the docs referenced all said 4 GiB.

Correction - stock FAT32 has that limit. I forgot that I fooled around with things with the editor from partition magic and a patch or two... Mike- -- Mornings: Evolution in action.

I feel comfortable about using tar. A primitive way to do my backup would be to make 2 tar-files: photos + documents 4,4 GB mail +.kde, 3,5 GB and burn them on each their DVD. Can I simply do that? If tar is OK with files around 4,5 GB is there anything special I have to worry about when burning the DVD (settings, formats etc)? Thanks! Janus -- Roskilde University, Denmark.
