On the one hand there are the 'snapshot management' types such as dev-dup and backintime that need to maintain a database and really are a dis-to-disk(-to-offline) so that the snapshots are easily recoverable
Need a big disk for destination. Can't use DVDs.
DVDS are under Cdn$15/100 on the street herefor the generics that sem to have a failure rate of less than 0.01%. I don't know what their lifetime is, but it seems to be at least 5 years :-)
SATA rotating Rust is about Cdn$50/Terabyte.
The real advantage to me of DVD is that I have lots of shelf space but not many drive slots or SATA ports.
Yes I know about external drives, but that gets into housing and power supplies. Ultimately its just as "off line" as the DVDs.
What we need is a K3B that is super-super smart, since I really don't fancy trying to all this with shell script.
I'm sleepy.
Let me say that the best backup program I have ever used was PCtools Backup, before the 90's. For MsDOS.
Hmmm.
I used it with floppies. It was so fast that I barely had time to write the label on the floppies. It formatted them on the go. It could verify them. It wrote the index of files on the last floppy, and on a file on the hard disk. A file could span more than one floppy. It did compression on the fly, and used forward error recovery (it could recover bad sectors).
It did full backup or incremental writing changed files automatically, taking note of deleted files too. I could define a list of directories and files to include or exclude.
I miss it. I don't understand how thirty years later there is nothing similar for DVDs on Linux. Or any other media.
Hmmmm. Sounds like a project. Who wrote the original, do you know?
there is dar, disk archive, which can make slices and span disks/cds/dvd/floppies and write indexes to disk. Dar (Disk Archive) is a hardware-independent backup solution. Dar uses catalogs (unlike tar),which it makes it possible to extract a single file without having to read the entire archive. It is also possible to create incremental backups. Dar archives can also be created or used with the libdar library (for example, with KDar, a KDE application). This package contains the command line tools and documentation. https://software.opensuse.org/package/dar there is also a gui available but not build for openSUSE, dargui. but it must be easy to build as I have it installed/working. -- (paka)Patrick Shanahan Plainfield, Indiana, USA @ptilopteri http://en.opensuse.org openSUSE Community Member facebook/ptilopteri Registered Linux User #207535 @ http://linuxcounter.net Photos: http://wahoo.no-ip.org/piwigo paka @ IRCnet freenode -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
