I am in the process of migrating our backup process from tapes to disk and implement Veeam at the same time. A full backup for us is 15tb and takes forever using our current system/software. I am looking for recommendations for a new disk based backup target. Veeam suspects we will need 100tb of storage for 5 years worth of data...this seems a like a lot to me.
Will 25+ NLSAS drives offer good performance or should I be looking at 10 SAS drives?
SAN, NAS, or Internal Storage?
Currently I am looking at Dell but have thought about Datto and Synology. Any other brands to look at?
I am looking to acquire 2 appliances so that I can have off-site storage.
Lastly, as a possible option...at our remote site I plan on using this appliance to also be the disk target for our DR recovery. So backup to disk at SiteA, replicate to SiteB, and if DR is needed, recover to the SiteB Appliance virtually.
Any suggestions/comments to help us would greatly be appreciated.
