Hi list -
One of my dumps is bailing out because I'm trying to fit too much data
using my 8505 8mm tape drive. I'm wondering if I can get dump to prompt me
to put in a second tape (if that's a good idea), or if I can set up my
backup scripts to only back up half the files in a particular
partition. I'm using a DEC Alphastation 250 4/266 running DU 4.OE (or
Tru64, if you prefer).
Too back up my partitions, I use commands such as:
at 21:00 January 11 /big/superuser/backup2-mondo2
The executable script "backup2-mondo2" consists of:
#!/bin/sh
dump -0unN /dev/rz1c
mt off
I have other scripts for other partitions, and one script backs up several
small partition on to a single tape. I know the 8505 tape drive is
theoretically capable of 10gb capacity with compression, but I've found
7-8gb to be more realistic. The dump script bails out with the following
message (that gets mailed to the root user because of the at command) :
... [extraneous beginning bits clipped out]
dump: 81.23% done -- finished in 00:38
dump: Rewinding and unloading tape
dump: Change Tape: Mount volume 2, tape # 0002
dump: Cannot open device file /dev/nrmt0h
dump: Cannot fopen /dev/tty for reading
query(): fopen(): No such device or address
dump: SIGTERM received
dump: The ENTIRE dump is aborted
Error on device named /dev/nrmt0h - Place EXB-8505 tape drive unit #6 ONLINE
Any suggestions? df -k reports the following usage for the /dev/rz1c
partition (in 1024k blocks):
/dev/rz1c 8749968 7278799 596172 93% /mondo2
That partition consists mostly of 45mb image files in TIFF format.
Thanks in advance,
Colin Brooks
PS To see why I use the backup strategies I do, please see my summary of a
query I submitted to this list in 1997 on good backup methods that's
