Silent data corruption is discovered when block A is read
Datto uses ZFS both on our devices and in the Datto Cloud for data integrity and efficient data compression.
How does it work?
Datto is a leading adopter of ZFS (the Zettabyte File System) both for backup storage in Datto appliances and in the Datto Cloud
ZFS is an advanced file system that is combined with a logical volume manager that, unlike a conventional disk file system, is specifically engineered to overcome the performance and data integrity limitations that are unique to each type of storage device.
ZFS provides copy-on-write snapshots, zero-copy writable clones, data compression and deduplication, support for massive storage capacities, as well as continuous integrity checking and automatic data repair.
With ZFS and Datto’s Inverse Chain Technology working together, Datto delivers the most advanced and complete BDR appliances and DraaS solutions available.
Datto's Advanced Storage technology with ZFS provides:
Data Integrity Protection
End-to-end checksums and data authentication to detect silent data corruption and automatically repair integrity
SSD accelerated and flash optimized:
Production-level storage performance from backup storage, while maximizing SSD service life for the world’s first all-flash backup
Maximum Backup Throughput:
Fast backups, even with a limited number of drives, via Write coalescing and an intelligent RAID
Including inline data compression, variable-length blocks, and inline block deduplication (Datto NAS)
Data Integration Protection
ZFS Integrity Protection
The system checks data at multiple levels to ensure the retrieved files are perfect copies of those that were backed up
- Phantom writes
- Data corruption on the drive
- Misdirected reads
- Accidental overwrites
ZFS sends verified version of block A to the application, and fixes failed copy on the drive
ZFS data protection and authentication protects data integrity along the entire I/O path. End-to-end checksums ensure that data integrity is not only protected on the drives, but also while it moves from drives into main memory. Controller bugs and DMA parity errors have met their match with ZFS.
SSD accelerated and flash optimized
- ZFS data compression
- Variable length blocks on drives
- Block-level data deduplication (now for Datto NAS 3)
- No more RAID mirroring (RAID 10) with a large number of drives
- No more wasteful duplication or copying of weekly full backups
- One copy provides both backup and instant virtualization or “instant restore”
- Unified storage and backup with Datto NAS 3 and NAS shares
- Backup Insights can locate any file within backup images without a file index database
Case Study: Avoiding Downtime Down Under
An Insurance Policy for your Data
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.
