Hey,
That's ok! We have actually tried Laservault and it was ... flakey... to
say the least, but this is the kind of product we would be looking for
if it wasn't so limited on speed and reliability.
Cheers
Mike

Hi, Michael:
Sorry, I guess I misunderstood your requirements. My bad. ...
(Also apologize for the duplicate post.)
You might want to look at a product like this one:
http://www.laservaultbackup.com/
and
http://www.laservaultbackup.com/index.php?q=node/6
and
http://www.laservaultbackup.com/index.php?q=node/11
Of course, you could also "roll your own" version of the above, with save files, then FTP them off to a PC server with large, inexpensive
disks.
HTH,
Mark

Hi Mark,we
That sounds very similar to what we have MIMIX doing at the moment -
currently have two boxes Live and Backup - the live system isreplicated
to Backup using MIMIXHA and then we currently backup the backup systemfull
every night (BRMS option 20) and finally a BRMS Option 21 on Sunday.
We're using probably at least 40 3590's a night and even more on a
backup.disks)
What I want to do now is replace the tape backups of the backup system
with an FTP server (which would be located externally to our business
and wouldn't necessarily run AS400 (probably not if we need cheap
and would no doubt be connected on it's own gigabit crossover cable.an
I will definitely look into some journaling scenarios as it might be
answer to a problem but it does sound to me like you're asking me tobuy
another ISeries (and buy more disks for that system which is one ofthe
biggest issues atm - especially for backups).Waterbury

Hi, Michael:
If your files are that large, why are you copying the entire file(s) over to another system, over and over again? Is this for "disaster recovery" purposes?
Investigate the remote Journaling support in i5/OS -- once you
an identical copy of the file(s) on the back-up system, you journalthe
file(s) on the primary system to the remote journal, and the changesare
automatically sent to the back-up system (via TCP/IP) andautomatically
applied to the copy of the file(s) on the remote system. So, you send
only the changes, not the whole file(s).
Or, you could "roll your own" approach to sending only the changes; instead of remote journaling, journal the files to a local journal and
journal receiver, and then periodically, (perhaps once a day), issuethe
CHGJRN command to start a new journal receiver, then save the existing
journal receivers into a save file, send the save file over to the back-up system, then restore the journal receivers and issue the APYJRNCHG command to apply the changes to the copy of the database file(s) on the back-up system. (A kind of "poor man's High Availability.) You could also write a program that reads the journal entries on the back-up system, after restore, and then applies the changes directly.Consider
Otherwise, you will be pumping terabytes of essentially the same data across the communications channel, over and over again.... :-o
the impact on other network traffic and bandwidth issues, etc..like

I would love to FTP my data on a nightly basis to another FTP server
this doesn't seem to be possible...backup
It appears that this is no issue what so ever if you are able to
to a SAV file and then FTP the sav file over.disk
Unfortunately my files are > 1tb and so I need double the amount of
space to do the backup.it
My questions:
1) Why do I need to dupe my data to achieve this, why can't I stream
straight over ftp?
2) Can I somehow split it up into many smaller files that can be sent
individually as the backup is processing and then cleared down?
3) How can I get cheap temporary disk space (preferably something
