Re: SAVLIB to FTP where files > 1tb

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 establish an identical copy of the file(s) on the back-up system, you journal the file(s) on the primary system to the remote journal, and the changes are automatically sent to the back-up system (via TCP/IP) and automatically 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), issue the 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.

Otherwise, you will be pumping terabytes of essentially the same data across the communications channel, over and over again.... :-o Consider the impact on other network traffic and bandwidth issues, etc..

HTH,

Having some issues here,

I would love to FTP my data on a nightly basis to another FTP server but
this doesn't seem to be possible...

It appears that this is no issue what so ever if you are able to backup
to a SAV file and then FTP the sav file over.

Unfortunately my files are > 1tb and so I need double the amount of disk
space to do the backup.

My questions:

1) Why do I need to dupe my data to achieve this, why can't I stream it
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 like
IDE?) that's not going to cost me an arm and a leg just for this?

Cheers guys, appreciate your time
