I recently tried to backup a ufs filesystem using vdump and directing
the output to an optical drive (pinnacle apex 4.6 Gb). The drive is
accessible as an rz device. The optical cartridge was formatted, but
not mounted at the time I ran vdump. I used the following syntax:
# vdump -0 -u -f /dev/rz21c /
and everything seemed to be going along quite fine, as this output
shows:
path : /
dev/fset : /dev/rz16a
type : ufs
vdump: Date of last level 0 dump: the start of the epoch
vdump: Dumping directories
vdump: Dumping 87213646 bytes, 188 directories, 1503 files
vdump: Dumping regular files
vdump: Status at Sun Nov 28 22:55:34 1999
vdump: Dumped 87213646 of 87213646 bytes; 100.0% completed
vdump: Dumped 188 of 188 directories; 100.0% completed
vdump: Dumped 1503 of 1503 files; 100.0% completed
vdump: Dump completed at Sun Nov 28 22:55:34 1999
Note: / was mounted on /dev/rz16a. /dev/rz21c is the optical drive and
was not mounted, although before I did vdump, I could mount it as a ufs
filesystem and copy files to it. I configured the optical using the
system_admin:configuration:disk tool under DU 4.0c
When I went to look at the result, I got the following error message:
# vrestore -t -f /dev/rz21c
vrestore: unable to use save-set; invalid or corrupt format
I'm afraid that either I'm missing something very fundamental about
vdump or it just doesn't work with this type of device. Any help is
greatly appreciated.
