ZFS and Third-Party Backup Product Issues
The following are the issues with the Veritas NetBackup and Brightstor ARCserve Backup
products.
Veritas NetBackup Does Not Back Up and Preserve Files With
ZFS/NFSv4 ACLs (6352899)
The Veritas NetBackup product can be used to back up ZFS les, and this conguration is
supported. However, this product does not currently support backing up or restoring
NFSv4-style ACL information from ZFS les. Traditional permission bits and other le
attributes are correctly backed up and restored.
If a user tries to back up or restore ZFS les, the NFSv4-style ACL information from ZFS les is
silently dropped. There is no error message indicating that the ACL information from ZFS les
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 8/07 release, both the tar and cpio commands correctly handle ZFS les
with NFSv4-style ACLs.
Use the tar command with the -p option or the cpiocommand with the -P option to write the
ZFS les to a le. 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 les. These commands correctly handle all attributes of ZFS les.
BrightStor ARCserve Backup Client Agent for UNIX (Solaris) and ZFS
Support
The BrightStor ARCserve Backup (BAB) Client Agent for UNIX (Solaris) can be used to backup
and restore ZFS les.
However, ZFS NFSv4-style ACLs are not preserved during backup. Traditional UNIX le
permissions and attributes are preserved.
Workaround: If you want to preserve ZFS les with NFSv4-style ACLs, use the tar command
with the -p option or the cpio command with the -P option to write the ZFS les to a le. Then,
use BAB to backup the tar or cpio archive.
