| Hello,
I make backups of my data in zip archives, which I burn to DVD and copy to a
USB hard disk, too.
I use the zip format, because I believe it's a standard which will last long
(and can be read from a lot of compression/decompression programs), so it
won't happen that I won't be able to read my backups anymore in future (as
opposed to proprietary formats of dedicated backup programs, I believe).
I work with audio, and it can happen that, from one backup to the next,
there's more data which a single (not double layer) DVD can contain.
For this reason I have to make several zip archives, and have to manually
select which files to add to one single archive, and have to guess if the
files which I select will have circa the size of DVD, compressed.
I prefer not use the usual spanning options of most programs, which can span
a single file to several archives, and treat the various spanned archvies as
one single archive. I want to be able to treat a single archive separately
(so the program should not span one single file to two or more archives, and
I want to be able to open the archives separately).
Is there a way to do this automatically? All the archiver programs which I
tried have the usual spanning option which I described above.
I would need this also to backup a full hard disk to many DVDs.
Thanks,
Thomas
