hey,

is it a kind of migration or what you want to do ?

For Replication you can use CA Licence.

If you want to do it offline, bring the new EVA in the same SAN, present a Disk and make a Copy?

Just an Idea...

yes it's good to connect it on the same SAN can u provide more of copy process is it easier? 

[mabu]

so.. i think

if you want to do an "Backup" or anything to bring the system up very fast i would to do this way.

- bring the systems on same SAN

- use weakly full backup on tape and a "OS based Copy" to second Disk(second eva)

- use incremental backup every day to tape

now you have a fast way to be online with only restore incremental backups to second storage...

you have to think about your requirements in case of failure before. Backup Time...RTO.....

a manual offline copy is not a HA Solution...

it is only an idea...

dear Mabu,

i attached the diagram that shows thae data flow from exsisting eva to other one by tapes to restore it on new one, look at the diagrame and give me ur suggesion.

[mabu]

hmm...

ok.. a question...

what is the reason to make a copy from backup ?

is it a DR Site? another building without a connection between?

i don´t understand the reason for this site.

almost DR site but no link between them and for costly i can't buy the CA license, so i want to use the backup tapes from exsisting to the new eva.

the question is : it's needs to use same configuration on exsisting site like eva volume pools and system linux configuration just i mean its professional to use the same.
