First time posting here; please take it easy on me, lol. I am looking for a budget device for office site backup copies. We have been using an older Synology DSPlay, but it just died. Having something that integrates with Veeam or that my Veeam server could directly connect to (network-based) would be nice. I would love to know what others are doing for a budget storage system for backup copies. We are currently backing up to a super micro storage server, syncing to Amazon, and I would like the local off-site option back in the mix. Hi IF you are doing local, Amazon (outside) I would suggest a local Immutable storage, Linux Server or a deduplicated immutable storage like HPE StoreOnce. But just to know, are you doing backups from veeam to Amazon S3? or other workaround to Amazon? Have you check Wasabi S3 Storage for cloud backup? Here you can see the link with some Veeam partners regarding storage:https://www.veeam.com/alliance-partner-integrations-qualifications.html?page=1
@Amore514: Just an idea for a different apporach. As you’re already copying your backups offsite via WAN/VPN, have you thought about offloading your backups to a cloud object storage (S3)? This would probably be more stable and offers you addtional security, for example immutable backups. Yep we are using the Amazon S3 storage, this works great but restoring is slow. Because of the slow restore i wanted something a bit more local and a 3ed set just in case. Playing devils advocate, would your WAN not be the bottleneck anyway in this scenario? I of course don’t know the detail of your platform here and might be completely wrong, have you tested a recovery to see the performance speed vs S3? Trust me i am open to all advice! Yes you are correct, restoring over the WAN would be SLOW! but this site is only 15 miles away, if i needed to restore everything i would pick it up and bring it to the data center :-)
I am almost a week in to turning off the write cache and so far everything is still working!

Hi @Amore514, write cache being disabled will certainly help. I had this with QNAPs years ago and had to remove this to resolve the problems. Unfortunately these QNAP/Synology grade systems are using software defined RAID controllers, with no battery backed write cache, meaning that writes can and do end up getting missed, leading to the corruption you’re finding here. It will ‘hurt’ performance disabling the write cache, but your writes will actually be hitting the storage prior to any confirmations, so it’s better to take the performance hit and then not have to worry about doing an active full due to corruption, any saved time is immediately lost here! I also want to clarify, are you using iSCSI over your VPN? or is it iSCSI to a local system that is accessed over VPN? If you’re trying to use iSCSI over VPN, this will be your biggest issue, iSCSI clients don’t like latency or fragmented/reordered packets, and you’ll be hitting a lot of both of these categories with iSCSI over
Looking forward to your feedback @Amore514 to see if disabling the write cache solved the issue. In general those NAS systems tend to be not too reliable and stable. Especially, in my opinion, the smaller consumer-grade ones aren’t built for such use cases like a backup target. So far I haven’t seen any problems with the bigger ones like the Synology rack systems. Do you know if any smaller inexpensive NAS systems that have a direct Veeam integration?
Not sure but maybe the difference is I am backing up over a WAN (Hardware VPN Cisco to Cisco), but like i also said in my OP i have been doing this for years to a USB drive with out any problem.Can you check if you have write cache turned ON or OFF? I would love to know. ISCSI is the way (unless you can use local disks) - better performance than SMB and NFS, I believe mostly due to multipathing. NFS would be preferred over SMB if you had to use a network protocol. That said, how is your volume formatted? REFS has been known to occasionally cause issues on ISCSI volumes to NAS’s and can be seen in the health checks at the end of the backups, or so I’ve read per @Gostev. With that said, I haven’t personally experienced it (to my knowledge...some of that is semi-transparent), but going forward, any NAS repo’s I have will be using NTFS and not REFS…..possibly might try XFS with a linux repo server, but haven’t done the research and tried it out yet. Edit: Just read your comment ab
After posting this, I found this linkhttps://forums.veeam.com/veeam-backup-replication-f2/synology-nas-as-repo-t77177.htmlMy ISCSI drive is formatted as NTFS, but I had the write cache turned ON for each disk. I just turned this off; I will report back in a few days. I will be surprised but willing to give it a shot if this works!
