Backup and Restore of Extended Attribute Files and Named Data Streams

NetBackup can back up and restore the following file attributes:

• Extended attribute files of the Solaris 9 UNIX File System (UFS) and temporary file system (TMPFS)
• Named data streams of the VxFS 4.0 file system

NetBackup backs up extended attribute files and named data streams as part of normal file system backups.

Extended attribute files and named data streams are normal files contained in a hidden attribute directory that relate to a particular file. The hidden directory is stored within the file system, but can only be accessed via the base file to which it is related. To view which files have extended attributes on Solaris 9 systems, enter: ls -@

Neither extended attribute files nor named data streams can be backed up or restored individually. Rather, the files are backed up and restored all at once along with the base file.
