Hi,

your information about 2 GB limit for 7.x IDS is true, (at least for 32
bit editions, not sure about 64 bit editions) but you can get around
the limit by using either a named pipe as backup device (which is not
treated like a file from IDS, more like a tape,
where there is no 2GB limit) or using a backup to a remote host (this
requires a working setup for rsh
(remote shell, with hosts.equiv, needs to work without password, TAPEDEV
like hostname:/dir/filename).
The latter can be done also for localhost.
The named pipe solution gives you the possibility to write a gzipped
file directly (as already stated below).

Hi Will,

a lil off topic maybe, but even using version 7.12 on SOL8 we used to
write to named pipe. On the other end we had gzip running.
We were able to write 6-7GB of compressed archiving data as soon as
large file support was turned on. Compression rate was like 1:4.
The disk space of these databases was around 25GB (sum of all npused).

But it is always better to test, if this is possible!
