how can we configure veeam 5 backup to readynas nv+? We have 2 readynas onsite and offsite, kindly suggest

Do you have any preferences as to how you would like to set this up for Veeam Backup and Replicator v5?

Is the NAS configured with RAID, because all you need to do is create a CIFs share, and then set Veeam Backup to backup to this CIFs share.

You also have a functionc called rsync, that can sync the data between both NetGear Readynas nv+ units, providing the two units can see each other, and the bandwidth between the sites is fast enough (1GB network).

otherwise Sync will be very slow, and maybe impossible.

Yes it is having RAID and I have already configured it for CIFS but I want to know what is the best recommendation on backing VM's thru Veeam on readynas nv+ and for offsite backup we have 2Mbps leased line dedicated between our HO and remote site.  Kindly advice

Use Veeam Backup to back to your CIF share on the readynas nv+.

So setup Scheduled jobs to backup to a Network Location. I would perform Incremental Backups as these will be faster, and less data (maybe) to sync with your offsite NAS.

The problem here is, 2Mbps is not very fast to transfer the data from one NAS to the other. It may take more than 24 hours to backup the contents from Site A to Site B, before it needs to transfer the next backup, is this a dedicated LINK for backups, or is it used by any other service?

You can use the Rsync technology in the NAS to complete this operation.

Do you know the size of your backups?

2Mbps is not dedicated it is used for overall connectivity. M planning to take bkp to cif share using reverse incremental bkp.  Our full bkp size 1.5TB, daily updates will be approx. 100GB I believe rsync will be better for bkp to offsite.  Let me know based on this bkp size what shud be the bandwidth
