Backup over WAN with Accellerator to DD

[Silece]

Hi,

we are currently planning our new backup conecpt with Veeam and EMC/DD.
One question that persists is:

If we use WAN Accellerator to back up or side office, the data will be dedupped for the transfer.
Question: Will the data on the main office side be dupped and then sent to the DD (which then
would use their own dedup algorithms) or
is the data going to be sent directly to the DD, so the EMC/DD algorithms would find allready
dedupped data and would have a hard time?

If this is the case, we do not need to buy a DD, but a MD or similar would do (with no dedup feature)

Best regards

Severin, if you're talking about Veeam built-in WAN acceleration used in backup copy jobs, then the data is deduped for transfer only (to avoid sending duplicate blocks over slow link), deduplicated blocks then are taken from the cache and written to the target storage to build up a restore point (to be further deduped by the storage itself). So there's no effect on the storage-side deduplication.

Hi,

Thank you for the information, that was exactly what I was looking for
