I am using ufsdump/ufsrestore to backup the filesystems
under Solaris 2.4 for SPARC. I use HP-DAT Drives C1533A DDS-2
and DDS-Tapes (90m and 120m). To do a backup over the network,
I use the following command:
rsh tmx ufsdump 0cfsd tmq:/dev/rmt/1n 15000 15000 /export/home/userdir
tmx - System where userdir is physically located
tmq - System with Streamer
/export/home/userdir - Directory to backup
This is done for each user.
I have two problems:
When doing a restore using
ufsrestore ivf /dev/rmt/1n ,
I get the message
Verify volume and initialize maps
Record size (512) is not a multiple of dump block size (1024)
This occurs only on some tapes a does not seem to be related to
the type of tape used.
It was possible to position the tape (mt -f /dev/rmt/1n asf XXX) and
to restore the data by doing:
dd if=/dev/rmt/1n of=tmpfile
ufsrestore ivf tmpfile
Well, finally I was happy...
Doing the backup on one certain host (tmp) , I get the following output
DUMP: Writing 63 Kilobyte records
DUMP: Date of this level 0 dump: Mon Feb 26 15:17:44 1996
DUMP: Date of last level 0 dump: the epoch
DUMP: Dumping /dev/rdsk/c0t1d0s7 (tmp:/export) to tmq:/dev/null.
DUMP: Mapping (Pass I) [regular files]
DUMP: Mapping (Pass II) [directories]
DUMP: Estimated 842018 blocks (411.14MB) on 0.02 tapes.
DUMP: Dumping (Pass III) [directories]
DUMP: Dumping (Pass IV) [regular files]
DUMP: Lost connection to remote host.
The backup-command nerver returns and therefore the other userareas
are not saved.
I hope somebody can help
