Backup Exec - duplicating data to offsite location

Hello

 

I have a customer who is seeking a new backup solution. He has around 17 servers with about 1-1,5TB of data. He has a backup server on his primary location that has a local disk array attached, where the backups are stored.

Now, he has an offsite location connected via high speed WAN (100 Mbps) and he want's to send a secondary copy of his backup data to this location.

His current backup software don't support this, so I am thinking of suggesting a Backup Exec solution, and using the duplicate feature to do the trick.

 

Has anyone made a similar solution/design or does anyone have any good recommendations on how to accomplish this? what about deduplication - would that be beneficial ?

 

thanks in advance :)

  • You can install a media server on both locations.  Both uses the dedup option.  After doing the backup, the dedup-ed data is duplicated across the link to the other dedup folder.  This is called optimised dedup.  You would also need a CASO licence.

    With this solution, only the changed data blocks would be transmitted across the link, thus minimising the bandwidth and time required.

    Thank you very much for your reply. But am I required to have a second mediaserver on the other location, if using a NAS or similar IP storage on the remote location ?

  • If you don't have a media server with the dedup option at the remote location, then you cannot do optimised dedup.  You can only either duplicate your backup or backup directly to the devices at the remote location.  This means that you would be sending a lot of data across the WAN link.  Unless your WAN has a lot of bandwidth and is very reliable, you are likely to end up with job failures.

  • It'll take some 40hrs+ or so to move 1.5TB over a 100Mbps link.  

    Without some sort of bandwidth reducing technology like deduplication or advanced compression, it's not physically possible.

    What pkh stated is correct

    1 BE server in Site A and another in Site B

    2 dedupe licenses, one for each BE server

    1 CASO option, so that it can manage the two BE servers

    You can now backup to a dedupe store in Site A, duplicate a backup to Media server in Site B.  Leveraging the Dedupe option, only a small amount of data will be sent, leveraging the limited bandwidth you have more efficiently.

  • thank you very much for your comments - that clarifies the solution I should go for !
