I'm receiving the error message "gbak: ERROR: unavailable database" in the
backup log when running a batch file via the AT scheduler on NT4.

This batch file used to run correctly, but recently I changed it to create
multiple backup files so that they can be copied to a CD. I am able to run
the batch file interactively, but the same script fails every night when
run automatically.

The script looks like this:

del f:\ib\delperf\backup.log
c:
cd \program files\interbase\bin
gbak -b -user sysdba -password masterkey -v -y f:\ib\delperf\backup.log
f:\ib\delperf\fds.gdb f:\ib\delperf\backup\fds1.gbk 525000000
f:\ib\delperf\backup\fds2.gbk 525000000 f:\ib\delperf\backup\fds3.gbk
525000000 f:\ib\delperf\backup\fds4.gbk 525000000
f:\ib\delperf\backup\fds5.gbk 525000000 f:\ib\delperf\backup\fds6.gbk
525000000 f:\ib\delperf\backup\fds7.gbk 525000000 f:\ib\delperf\backup\fds8.gbk


Any help appreciated.
