Offsite replication of a De-dup folder

Created: 18 Sep 2012 | 1 comment


I am looking for advice on how to optimise my backup and disaster recovery problem.

I have a small shop that is using backup exec 2010 R3.  We only have about 400GB of data to backup,  I sucessfully backup to a de-duplication folder on a local disk array.  Full backup is done on Friday and incrementals are done M-Th.  The question is how to store the back data offsite without tape.  I have a VPN connection to a remote site with pleanty of storage - but the pipe is slow.  It can only do about 23 MB per minute.

The question is: whats the best methoid of replicating the data offsite using the VPN?

I tried a job where it just backed up the de-dup folder - setting a full backup one a year and incrementals for the rest of the year.  That worked but I noticed that the data being moved during the incremental backups was far too low - only 1000 bytes or so - I thought maybe it had something to do with the archive bit?  Could I tweek this to make it work?

I also tried duplicating backup sets after my local job finishes, but it takes far too long.  Each friday the new full backup would finish in a few hours, while the duplicated backup set would take about a week... 

Any and all advice would be appreciated.

Hello there.

    You can use the CAS-MMS setup and then use the Optimized Deduplication option to backup the data to the remote server through limited bandwidth channel.

Check this technote : : Copying deduplicated data between deduplication storage folders or OpenStorage devices by using optimized duplication

To perform optimized duplication between a central administration server and a managed Backup Exec server, the following WAN requirements must be met:

  • Less than one percent packet loss during transmissions
  • Less than 250 milliseconds network latency (round trip)

Few more technotes for reference" : Seeding Before Running an Optimized Duplication Job : Best practices for using Backup Exec 2010 R3 Deduplication Option with the Central Admin Server Option or the SAN Shared Storage Option



Hope this piece of Information Helps you... and if it does then mark this response as Solution....!!!
