Hallo,
I have been using an internal Iomega Ditto 2G tape for some time now to
make backups - both in Dos and in Linux.
In Dos, it works wonderfully well and efficient. However, as soon as you
want to verify or restore backups made using Linux frustration starts:
A lot of errors start showing. Over the weekend I was trying to restore
from a recently made backup which was made using dump. Restore ran for a
few hours without restoring a single file from the selection I made and in
the end gave up with a hardware error notice.
I then got hold of a new tape, made a backup using tob. I cannot get tob
to read back from a backup made by tob so I used afio to verify the
backup. It has been running now for about 12 hours and did not finish the
job yet. There is about 1 gig data on the tape compressed to about
560meg. This is just not acceptable. When done in Dos it takes about 3
hours to backup and verify 600 meg of data.
Is there hope for a reliable backup and restore program in Linux? I have
tried tob, tbackup, dump and restore and no one so far could give me the
impression that the system is reliable.
