Offsite replication of a De-dup folder
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.
