I'm searching for a linux backup solution. And flexbackup is almost it!
There are three things that make me continue looking for other solutions:

1) Crashev has asked these questions (twice):
> My question is - how to restore fully latest backup ? I mean if my
> system fails today and I want to have the freshest backup restored -
> how to do it with flexbackup? Should I extract fullbackup with *.0.*

These are *very* reasonable questions to be asking of my backup system.
How do I reliably recreate the "last good state"? Any backup system that
can't answer these questions are not up to the job, IMHO.

2) Pablo Godel asked: incremental backups and deleted files

Basically, if I delete files and make incremental backups, the deletion
of these files is not recorded in the incremental backups. So no, it is
in fact impossible to reliably get to the last good state.

Also, FAQ "How do I find out which archive(s) contain a certain file?"
on http://www.edwinh.org/flexbackup/faq.html mentions:

> If you don't know in which archive to find a certain file, look at

No, that doesn't work very well. It *sucks*! (Especially if you have to 
  restore 12342345 files and you don't know what they are.) There seems 
to be no way to automatically and reliably restore/extract a backup set.

Adding just a little meta-data to the created backups could enable this
functionality: I'm thinking a -search option to find the relevant 
archives and -restore to extract from the relevant archives.

3) There are three Project Admins: edwinh, jjreynold and pholcomb.
EdwinH, the only one to ever post to the mailing list, last did so
2004/01/30 - over two years ago. Basically the project is without
contributors and maintainers.

I'm tempted to take a stab at adding the meta data to the created and 
backuped data and implementing -restore and -search. I've just never 
used a tape backup system, only to-disk. Would anybody we willing to 
test any such enhancements on a tape-drive?


# I'd like to be able to restore src with newest file2,
# file3 and file4 in it. (And no file1)
# Impossible with current flexbackup, though.

mkdir src

echo line > src/file1
echo line > src/file2
echo line > src/file3
echo line > src/file4
flexbackup -c flexbackup.conf -set test -level 0

rm src/file1
echo anotherline > src/file2
chmod go-rwx src/file3
ls -l src

sleep 60
flexbackup -c flexbackup.conf -set test -level 1
