Richmond, some features of ZFS (it has more features than this)
1. Checksums in Metadata for Data Integrity - meaning it can detect more errors and has more integrity than EXT3 that uses block checksums. 2. Copy on write - means that writing to a file is a transaction, or it happens correctly or it doesn't happen. It can't break because the old data of the file is retained and can be rolled back if the checksums after writing fail. 3. Data snapshots - You know that time machine thing that apple fakes using incremental backups? Well ZFS has snapshots at file system level. You can configure it to snapshot things every 15 minutes or every hour and you can roll back time if you need. 4. ZFS has a pool - ZFS volumes are packed together in a zpool and you can add or remove disks as needed to the pool. You're running short on disk space? Just add another disk to the machine and add it to the pool, space magically appears. 4.1 ZFS can create hybrid SSD/HD pools using the SSD as a high speed file cache for often used stuff and the HD for long term storage. 5. Data scrubbing - ZFS can use the checksum to check all files in the zpool and if you're using something like RAIDZ to mirror the data, it will recover errors silently with no admin intervention between the mirrored stuff. These are some basic features that everyone should have on their FS! At this moment Solaris has the best ZFS support followed by FreeBSD. ZFS is one of the things that Linux could really use.
