Re: Back ups with High Availability Web Server

One technique I use to back up IFS/DLO in the senario your relating Brad is to use SAVRST and SAVRSTDLO. Those commands have options to only pick up new objects since the last save. I set it up in a program that will submit itself to run in two hours again, then backup whatever has not been backed up before. On systems like your suggesting the backup usually runs about 10 minutes along with the restores on the target machine. Not perfect replication but way better than over night. Additionally since the backups are running every two hours, the nightly save can forget about the IFS/DLO altogether. Now I don't care about the locks, I'll get the object in the next two hours anyway.

SWA on the IFS / DLO are in my experience not worth the time to type the characters out.

We are talking about the majority of the data, and what's taking so long,
are the IFS objects. Not really any data in QSYS.LIB.

I only mention this because there seems to be a little confusion, and I've
experienced in the past when they're saving an IFS object, that entire
directory is locked until it's done. And locked down hard.:)
