We are currently looking at the possibility to do unattended backup on our AS400.
We are running a bank but every day we need lo load tapes and perform backup
using the traditional backup commands.

Any suggestions?

One option would be to backup into a save-file and automatically FTP that save-file to another box (of whatever sort). Of course, that'll require significant amounts of setup and coordination, but that's the case with pretty much anything you implement. Also, you'd probably need significant amounts of free disk space to hold the (probably large) save-file.

There are other options, but that's the first one that came to mind.

Before any decisions are made, what exactly does your current daily backup include? That is, are you only backing up data? Or are you including IBM libraries as well? Configuration data? Security data?



@ DaveSlash: We also thought of that possibility but we are talking about 20gb save files which would take too much to FTP to remote locations .

@Tom: We only backup data libraries (no conf/sec data)

Thanks Gary. This is exactly what I need. Best regards, Errol
Note that if you don't have sufficient space for savefiles, it's pretty much guaranteed that you won't have space for virtual tape.

But if you are saving multiple libraries, you would be saving each one to a separate savefile. (This could be done to a separate virtual tape volume also.) As each single save operation completes, you might migrate that individual savefile to an archive location. Then the next library could be saved after the previous save area is cleared.

The limitation will be how much spare space is needed to account for your single largest save operation.
