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.
I meant that the software you mention is designed for doing the backup to a single huge destination hard disk. Thus, can not be used with 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.
Verbatim M-DISC 50GB seems to be 0,259€/GB. Verbatim Bd-R-M 25 GB seems to be 0,20432/GB. Verbatim M-Disco Bd-R Xl 100 GB seems to be 23,26€/disk, so 0,23/GB. Ah, found a box of 5, 91,82€, thus 0,18364/GB. Archival quality, they say they last a millennia.
Yes I know about external drives, but that gets into housing and power supplies. Ultimately its just as "off line" as the DVDs.
Well, you can use a caddy box. Insert a disk, do the backup, remove and store. And it is far easier to backup to a HD than to a number of DVDs. Plus, we know how to encrypt hard disks. - -- Cheers, Carlos E. R.
