When it comes to dumping and restoring filesystems, there is still no
official
replacement for the ufsdump and ufsrestore.
Let's go into that a little bit. If you're piping zfs send directly into
zfs receive, then it is an ideal backup method. But not everybody can
afford the disk necessary to do that, so people are tempted to "zfs send" to
a file or tape. There are precisely two reasons why that's not "officially"
recommended:
"Officially" yes you have it in quotes but where is the official
reference for this ?
In fact I'd say the opposite. In Solaris 11 Express the NDMP daemon can
backup using dump, tar or zfs send stream.
This is also what the 'Sun ZFS Storage Appliance' does see here:
http://www.oracle.com/technetwork/articles/systems-hardware-architecture/ndmp-whitepaper-192164.pdf
On page 8 of the PDF titled: "About ZFS-NDMP Backup Support"
It does point out though that it is full ZFS dataset only, but
incremental backup and incremental restore is supported.
This has been tested and is known to work with at least the following
backup applications:
• Oracle Secure Backup 10.3.0.2 and above
• Enterprise Backup Software (EBS) / Legato Networker 7.5 and above
• Symantec NetBackup 6.5.3 and above
