The following are the issues with Brightstor ARCserve Backup products.
The BrightStor ARCserve Backup (BAB) Client Agent for UNIX (Solaris) can be used to backup and restore ZFS files.
However, ZFS NFSv4-style ACLs are not preserved during backup. Traditional UNIX file permissions and attributes are preserved.
Workaround: If you want to preserve ZFS files with NFSv4-style ACLs, use the tar command with the -p option or the cpio command with the -P option to write the ZFS files to a file. Then, use BAB to backup the tar or cpio archive.
