Advanced Storage

Datto uses ZFS both on our devices and in the Datto Cloud for data integrity and efficient data compression.

Datto makes extensive use of ZFS (originally known as the Zettabyte File System) locally and in the cloud for maximum data integrity protection, storage efficiencies, and performance. ZFS is a combined file system and logical volume manager which revolutionizes the way data is recognized and organized within servers. It is built for efficient data compression, support for large storage capacities, and protection against data corruption.

ZFS integrates filesystem and volume management, enables snapshots and copy-on-write clones, as well as continuous integrity checking and automatic data repair, and RAID-Z. Utilizing these technologies, Datto has built a resilient Backup, Disaster Recovery, and Business Continuity platform untethered by legacy backup strategies built for old technology. Just another way Datto ensures Total Data Protection.

Datto's Advanced Storage with ZFS provides:

  • Copy-on-write snapshots: Use write coalescing to create immutable snapshots that keep each recovery point fully constructed
  • Data integrity: Checksums at all levels, even against DMA parity errors
  • SSD acceleration: Enabling 6 second in-place recovery while providing production level storage performance
  • Data reduction: Including inline data compression and inline block deduplication

A commitment to ZFS

Datto systems begin with great hardware and expert build quality, but great software is required to harness that potential. It starts with the OS and the file system, and Datto selected ZFS as it is the most powerful, flexible, and trusted file system available. Datto has committed to embedding ZFS into all of its systems. This includes Datto SIRIS, ALTO, and Datto NAS. The servers that Datto manufactures for its the 250+ PB Datto Cloud also all use ZFS. With ZFS, Datto systems are capable of bringing enterprise IT capabilities to the masses but without the enterprise price tag.

Rapid and intelligent directory comparison

The Backup Insights tool is extremely easy to use and can be accessed right from the user interface. In a matter of seconds you can simultaneously mount points and see all files broken down with an easy to read file tree. The reason this is uniquely fast on Datto BDR solutions is because each and every backup is always in a fully constructed state, thanks to Datto's Inverse Chain and advanced storage technology. Flipping through backup "views" is immediate and fluid, whereas competitive solutions would have to reconstruct different points in time from chains of full and incremental backup files.

By default, Backup Insights intelligently excludes the Windows directory for any OS volume, as these directories can have a lot of changes and/or be very large. You can choose to have the restore rebuilt with that volume included by simply selecting the Windows folder. You'll then be presented with a view of the changed files within the Windows directory.

ZFS performance benefits can reduce backup windows dramatically, leading to improved RPO and RTOs. This is because ZFS:

  • Integrates RAID intelligence with the file system for balanced and optimized use of storage drives.
  • Only writes logs that have been coalesced into 128KB blocks to free locations.
  • Write coalescing overcomes HDD limitations on operations per second by consolidating scattered writes into a few large sequential operations
  • Inline compression and deduplication further reduce write IO transactions

Copy-on-write snapshots

One of the the greatest features of ZFS, and an enabler of Datto's Inverse Chain Technology, is its built-in Copy-on-write snapshots. Since ZFS redirects all writes, Datto can create hundreds of snapshots with effectively zero cost in terms of space, or computational resources to create those snapshots.

With "Copy-on-write" snapshots, each block of data in each snapshot references back to the original blocks. It is also what enables a Datto BDR to instantly virtualize without requiring a backup dependency chain, because with Datto every recovery point is always in a fully constructed state. With the "Copy on Write" capability, we can clone one of those snapshots, using copy-on-write feature to create that clone, and spin up VMs quickly

Case Study: Avoiding Downtime Down Under

Discover how a proper BCDR not only offers peace of mind for the end user, but for the MSP as well:

"With an all-in-one solution, bolstered by technology like Screenshot Backup Verification, Addictive Technologies takes the guessing game out of BCDR. Now that we have implemented Datto, we know that the restores are happening and being tested daily by the Screenshot technology... Naturally, we all sleep a lot better now."
