Which Level of NBU DC 4.5 Is Stable?

[Charles]

I have had the most frustrating exp with NBU 4.5 DC. FP3 When it works it works well, but that’s the caveat "When it Works" Here's a rundown of my latest fiasco.... If some one could tell me if I'm just fighting a Bad release?

Environment is as follows:
Sun 480R 4Way 16GB Mem
Netbackup 4.5 DC FP3 as Base Install
STK L700e 6x9940B SAN Attached Tape Drives
8 SSO - SAN Media Manager - All work great except one, which is dog slow (Event with multiple streams etc....)

We don't use vault, but except that our installation is stable.
We use FP5 on master and media server, and the clients use GA, FP3, FP4 and FP3

Thank you for the response. Just thought maybe some would say "Hey! FP? Is much more stable. Vault is soooo slow, going to look in to the duplicate scripts.

Regards,

We had a specific error in FP4 regarding the library control on the L-series libraries from StorageTek, but that was fixed in FP5.
I realy don't remember anything else.
But we are an Windows only shop

Charles,

I have no experience with Vault so don't know if this applies. We run manually scripted bpduplicates.

If your backups are multi-plexed, make sure you use the -mpx parameter in your duplicate command. (assuming you don't mind you duplicates being mpx'ed).
