|
|
* Object level mirroring and striping
|
|
* Checksums on data and metadata (multiple algorithms available)
|
|
* Compression (multiple algorithms available)
|
|
* Reflink, deduplication
|
|
* Scrub (on-line checksum verification)
|
|
* Hierarchical quota groups (subvolume and snapshot support)
|
|
* Integrated multiple device support, with several raid algorithms
|
|
* Offline filesystem check
|
|
* Efficient incremental backup and FS mirroring (send/receive)
|
|
* Trim/discard
