Disaster Recovery

Hi everybody,

We are currently thinking about solutions to recover one or more AS/400. We 
will probably buy a new AS/400, but we don't want to use mirroring or external 
software. Knowing that AS/400 has no activity between 6 p.m. and 8 a.m., I'd 
thought using following method :
- A total system safe ("go save" 21) on tape once a week on saturday morning. A 
copy of the tape will be sent to the backup by postal mail.
- At end of each production day, save all modified objects (SAVCHGOBJ) and send 
it to backup by using file transfer.
- 4 or 5 times a day, save the JRN files and send it to backup by using file 
transfer too.

Do you think that this solution will work ? I don't have too much doubt about 
the first 2 safes, it's only a matter of volume of data and of network speed. 
But is it possible to save JRN files without stopping corresponding tasks and 
to restore them on backup side ? Our OS is a V4R5 on a 820 and we will surely 
migrate to a new 520 in V5R3 of course. 820 will become our backup machine. 
Does V5R3 offer new possibilities in saving and restoring ? Pehaps by making 
the things easier ?

Thanks for your assistance.
