まあ、もうすぐ製品版の Solaris にものるから、使われるようになったらすぐわかるよ。 だけどさ、特定のデバイスドライバとかと違って汎用のファイルシステムで、 しかも UFS に代えてこれから主流として使おうってもんなんだから、 一応 Fire E25K とかのハイエンドで業務利用するのも視野に入ったレベルで 実装がすすめられてるわけで、とりあえず入れてみました、この先実用まで たどりつけるかどうかわかりません、てないい加減なもんでは少なくともないわな。 Linux のガラクタファイルシステム群といっしょくたにすんなよな。
Note that these still don't do any crypto yet, I'm debugging a problem in the ZIO pipeline with zfs_write_encrypt not getting called when I expect it should. --
Creates a snapshot with the given name. See the "Snapshots" section for details.
zfs backup [-i snapshot] snapshot2
Creates a backup of snapshot2. The backup is written to standard output, which can be redirected to a file or to a different machine. For example, using ssh(1). By default, a full backup is performed.
-i snapshot Perform an incremental backup from snapshot to snapshot2.
The format of the backup archive is evolving. No back- wards compatibility is guaranteed. You may not be able to restore your backups on future versions of ZFS.
However, that feature didn't arrive until years after the initial product rollout. I think that having a stable product is more important in the short term than having a product with every feature.
Once ZFS has been out (and on the system disk!) a year, the feature should be in the product.

First alpha of ZFS on FUSE with write support Ladies (?) and gentlemen, the first preview of ZFS on FUSE/Linux with full write support is finally here! You can consider it my (late) Christmas gift for the Linux community ;) Don't forget this is an alpha-quality release. Testing has been very limited. Performance sucks right now, but should improve before 0.4.0 final, when a multi-threaded event loop and kernel caching support are working (both of these should be easy to implement, FUSE provides the kernel caching).
