Backup to disk to disk solution over a WAN

[chris48]

I have a remote site which is not manned but requires regular backups. I am planning to implement a Backup Exec 2014 server with a deduplicate storage disk where I will run daily backups and then run a duplicate job to backup to a remote Backup Exec server over the WAN in our main office.  This server (office server) will also have a deduplicate disk to where the backups will be replicated to and I will then run another duplicate job against that to tape.

I want to know if I can do this without the CASO option or is this a requirement for duplicating deduplicated backup sets?  If anyone has any advice regarding this, Backup Exec versions, options, agents, etc that would be great and also any other advice generally related to this implementation.

Thanks

Chris

Hi Chris,

It's called Optimized Deduplication and you need CASO for it to work.

Read below:

Without CASO the solution will not work.

Thanks!

CASO is needed to share the dedup folders.

So CASO is higly recommended, but in a one-to-one scenario (one BE server opt-dupping to another) not mandatory. BE 2014 Admin Guide: "If you use the Central Admin Server Option (CASO), the functionality of optimized duplication is expanded to let you do the following:"...

CASO is required in order to get both media servers to communicate with each other. Without that, neither server will know of the other, much less the dedupe folder you are trying to duplicate too.

CASO controls the catalogs as well meaning that if your primary server crashes, the media server on the remote site can restore data when you need too.

I have one question regarding the WAN link between the 2 sites.  I believe Symantec recommend a 1 gigabit connection, but I wondered if this would still work with a 100 megabit connection or would I experience issues with this?
