Should I use my backup software's built-in dedup or a dedicated appliance?
Built-in dedup from Veeam, Commvault or NetBackup is enough for many environments and simpler to manage. Dedicated appliances like ExaGrid or PowerProtect DD earn their place at larger scale, longer retention or when restore speed is critical.

Best Deduplication Software in 2026: 8 Tools Compared
What is data deduplication?
Deduplication eliminates redundant copies of data so only unique blocks are stored. If a hundred backups all contain the same operating system files, dedup stores them once and references them everywhere else, cutting storage needs dramatically.

Best Deduplication Software in 2026: 8 Tools Compared
How much storage can deduplication save?
It depends entirely on the data. Virtual machine and file-server backups commonly see 10:1 to 20:1. Encrypted, compressed or unique media files may see almost nothing. Always test with your own data rather than trusting datasheet ratios.

August 9, 2023 - If I read about deduplication, it is always ZFS or BTRFS but LOTS of RAM needed. Or OpenMediaVault with BorgBackup... but the client also needs BorgBackup (and Clients will Windows still) ... Don't know where the "LOTS of RAM needed" comes from. Sure, if you build a high-performance NAS for dozens of clients and dozens of disks, then even modest buffers as desirable for maximum throughput become a couple gigabyte in size, but that's absolutely not your use case.

We already use some smaller modelles at remote sides withot Veeam, but we have 0 experience with other vendors. ... The most important consideration is not backup performance, but restore performance. Because ExaGrid is the only dedupe device to use a landing zone, it can recover from this 'normal disk' area without having to rehydrate deduped VMs.

January 22, 2019 -
I am thinking of purchasing a cheap NAS drive which supports RAID1 and if possible some kind of deduplication. Does anyone have any opinions regarding this subject?
I am currently using an old desktop PC which I installed linux on one drive and managed to configure software RAID on a couple of 2TB disks. It works fine but all other components apart from the 2TB disks are around 10 years of age. Also a NAS would be smaller, consume less electricity and have a decent management interface.

While everyone goes straight to ZFS when the topic is deduplication, there are now other options... Such as VDO.

If you ignore the dedupe requirement then pretty much any Netgear, Synology, Qnap, Drobo, etc. will work for you. Low power, features most people want, decent throughput, and if you pony up a little more you can get one with a CPU good enough to transcode video. Ignoring the technical requirements to deduplication, what is your use case? Mail servers--yes lots of the same dang message forwarded around so plenty of opportunity for space savings. Same with sharepoint sites, things with lots of text, and if you plan on leveraging snapshots (iSCSI most likely in home usage) for actually doing something like VM cloning. Otherwise you're going to barely make a dent in compressed videos, if anything at all, which is the biggest space hog for most people. And you'll pay for it dramatically in terms of either power, raw $$, or time investment to maintain a roll-your-own system.

r/sysadmin on Reddit: Backup Storage and deduplication solution
August 26, 2021 -
We currently use Dell/Quest's DR 6000 series storage/dedupe appliance and for our needs its been running fine. However, we are now somewhat forced to find a new solution as its no longer offered and will be EOL soon. We used datadomain in the past and while its a great product, its just too expensive for us.
I've checked on reddit and the posts around this topic are at least 2-6+ years old, hence thought to post, maybe there are better alternatives now that we're not aware of. We have also looked at Avamar, and its undoubtedly an overkill for us. Quest has suggested QuorStore but don't know much about it. We have a mid size environment and dedupe appliances make sense because then you don't have to worry about 200+TB of disk arrays for example. However, we're also open to explore dumb disk storage options, but will need some kind of nfs/cifs in the front for our backup software to be able to write to it. Based on what I read online, most vendors want to sell backup software with the hardware which isn't what we're looking for, I guess that probably shrinks our options a bit.
Would appreciate any ideas or suggestions.
Thanks

We use Veeam and use cheap physical servers+JBODs from Supermicro. The space savings you get with Veeam's ReFS/XFS fastclone feature means dedup isn't nearly as beneficial. Though it is possible to use Windows Server's built in Deduplication as well (with some caveats on how it's set up). My opinion is the amount of money that "enterprise" storage vendors charge for a deduplicating appliance makes the value you get out of the space savings not really all that great compared to buying dumb storage from a low cost vendor.

One more vote for Veeam. It is an amazing product. I've tested it myself with backing up and restoring to different hardware, works great. You can additionally extend it by rclone or something similar to push backups to offsite NAS or cloud storage. Here are the most useful tools to combine with Veeam: https://www.vmwareblog.org/single-cloud-enough-secure-backups-5-cool-cross-cloud-solutions-consider/

What is Data Deduplication? | Barracuda Networks
January 28, 2026 - With deduplication, just one copy of these individual virtual machines can be stored. Everytime the engine discovers a piece of data that is stored somewhere else in the storage environment, the storage system saves a small pointer in the data copy’s place, thereby freeing up the blocks that would normally be occupied. As you might expect, different vendors handle deduplication in different ways.

April 27, 2025 - Deduplication is turned on by default, and the system automatically runs it on all volumes and aggregates without any manual intervention. The performance overhead is minimal for deduplication operations, because it runs in a dedicated efficiency domain that is separate from the client read/write domain. It runs behind the scenes, regardless of what application is run or how the data is being accessed (NAS or SAN).

What methods does QES use to perform data deduplication? | QNAP
July 3, 2019 - Offline deduplication: Deduplication is performed on data after it has been written to disk, according to a schedule or other trigger. QES uses inline deduplication, which means that it deduplicates data after receiving it from a client but before writing it to storage. Inline deduplication reduces the amount of data written to drives, which reduces drive wear. This is especially important for NAS devices containing SSDs, as SSD lifespan is highly dependent on the total number of write operations.

Pure Storage has all-inclusive licensing. Every feature is included with the price. At this point, I can't imagine anyone charging for compression or deduplication.

AFAIK all of those vendors include Data Reuction as standard in the price, with one exception... Pure FlashBlade, if purchased via their Everygreen//One model, does NOT include ANY data reduction in the price. You pay based on the written capacity. So if you write 1TB of data, you pay for 1TB of data, even if it only needs 100GB of actual storage to store it after compression. Also keep in mind that not all products support the same types of data reduction. eg, Pure FB doesn't support Dedup at all. (And just for full disclosure, I work for VAST, and formerly worked for Pure)
