The Veritas NetBackup product can be used to back up ZFS files, and this configuration is supported. However, this product does not currently support backing up or restoring NFSv4-style ACL information from ZFS files. Traditional permission bits and other file attributes are correctly backed up and restored.
If a user tries to back up or restore ZFS files, the NFSv4-style ACL information from ZFS files is silently dropped. There is no error message indicating that the ACL information from ZFS files has been dropped.
Support for ZFS/NFSv4 ACLs is under development and is expected to be available in the next Veritas NetBackup release.
Workaround 1:
As of the Solaris 10 7/07 HW release, both the tar and cpio commands correctly handle ZFS files with NFSv4-style ACLs.
Use the tar command with the -p option or the cpiocommand with the -P option to write the ZFS files to a file. Then, use the Veritas NetBackup to back up the tar or cpio archive.
Workaround 2:
As an alternative to using Veritas NetBackup, use the ZFS send and receive commands to back up ZFS files. These commands correctly handle all attributes of ZFS files.
