Backing up Solaris Zettabyte file systems
On Solaris SPARC and Solaris x86 systems, you can backup Zettabyte file systems (ZFS), by using ZFS snapshots. The advantage of this approach, over an ordinary incremental or selective backup, is that the files and folders in a snapshot are always in a read-only state, so they cannot be changed during a backup.
About this task
You create a ZFS snapshot by using Oracle Solaris
ZFS commands. For example:
zfs snapshot tank/myZFS@mySnapshot
In this example, the ZFS pool name is called tank and the ZFS file system name is myZFS. Files that belong to this ZFS snapshot are in the subdirectory named tank/myZFS/.zfs/snapshot/mySnapshot/.
Procedure
Use either of these two methods to backup a ZFS snapshot.
