what is the backup practice using the netapp snapshot

[zhangfred_vm]

Dear experts,

I am using the netapp 6070 as the storage and I want to design a backup solution using the netapp snapshot techolgy.

Is there some best practice documents?

THanks.

You can use VCB for backing up - maybe netapp has some solutions for you.

here's what we do. script doesn't work for you, but you can take this as a hint.

perhaps it helps.

You shouldn't be doing things in the service console as it will be going away - at least in ESX 3i. I would recommend using a backup proxy server with VMware Consolidated Backup and using a 3rd party app if necessary.

And where do i run my hp insight agents then ?

I want my console !!

This GUI stuff is nice for daily work, but if something goes wrong, the console is my friend.

Perhaps they're doing this 32MB Hypervisor thing and theres no room left for a console ?!?

What if my backup proxy crashes ? I've no backup at all, if my esx crashes, i've some other Problems.

haha ... yeah, I think for you, the console might be good, but I think it's a source of problems for others as it's not linux. So, your HP insight agents will be available as they'll have their hooks in. The backup proxy is a separate box that has VCB installed. If your ESX box crashes, it would be a shame. You can still make backups via the VCB.
