Supported save set configurations for UNIX hosts

The Client Configuration wizard does not display some types of file systems on UNIX hosts and these save sets are not in the ALL save set.

When the backup starts, the savefs process reads the contents of the /etc/vfstab file on Solaris clients, the /etc/fstab file on HP-UX and Linux clients, or the /etc/filesystems file on AIX clients. The contents of the file are compared to the currently mounted file systems and BTRFS sub-volumes. Only currently mounted file systems and BTRFS sub-volumes that are configured in these files are backed up. When NetWorker encounters a sub-directory that has a sub-volume ID that differs from the parent sub-volume ID, NetWorker will not backup the contents of the subdirectory, unless you specify the save -x in the Backup command field or select the Cross mount points enabled option in the properties of the Client resource.

If you edit a client resource and modify the Save set attribute to include file system objects for file systems that are not in the OS file system file, NetWorker will not back up the file system objects.

The following file systems are excluded from the ALL save set. If you manually define the file system or directories and files for one of these file systems in the Save set attribute of the Client resource, the backup operation excludes the object:

Table 1. File systems excluded from the ALL save setThis table specifies the file systems excluded from the ALL save set.
hsfs proc fd cachefs lofs mntfs ctfs objfs	sharefs nfs2 nfs3 nfs3perf profs nfs4 nfs brfs	dfs autofs iso9060 udf sysfs debugfs subfs usbdevfs	binfmt_misc usbfs devpts cifs swap tmp tmpfs nucfs	nucam fdfs xx none

When you specify the ALL save set:

For a Solaris sparse or whole root zone client, all mounted file systems in the sparse or whole root zone that are not normally skipped, such as NFS, are backed up.
ZFS file systems are backed up.
If the save set name includes a symbolic link, a save set recovery is not supported.

Use a customized ALL save set to backup files.
