Data Backup 12-3
File type, including UNIX symbolic links and hard links
File size
DOS name, attributes, and create time
Windows NT ACLs
NOTE: The CIFS attributes (DOS name, attributes, and create time, and Windows NT
ACLs) can be restored only with the filers restore command. You cannot use the
Solaris ufsrestore command to restore these attributes, although the
ufsrestore command can restore the data in CIFS-created files.

Options in the dump command enable you to exclude certain types of data from the
backup.

You can choose not to back up Windows NT ACLs if the data is used only by NFS
clients.

You can choose to exclude files and directories from a backup if you do not need
those files and directories again. For example, you can exclude temporary files gener-
ated by some applications or object files produced during program compilation.
When the dump command traverses the dump path, it compares file and directory
names to each exclude string specified in the dump command. If the name exactly
matches the string, the file is excluded from the backup.
NOTE: You can reduce the amount of backup data by using an exclude list in the
dump command. However, an exclude list increases the amount of time needed to
finish a dump command because the filer must compare each file name to the
exclude list to determine whether the file should be backed up.

The dump command can back up data to these devices:
Tape drives or tape stackers attached to the filer
Tape drives or tape stackers attached to another computer, provided that the fol-
lowing requirements are met:
The computer supports the rmt protocol.
The filer has a trusting relationship with the remote computer to which the
tape drive is attached. This relationship enables the filer to write to the tape
drive. For example, if you want to back up the filer to a tape drive attached to
another filer, include the filer in the /etc/hosts.equiv file of the destination
