In the example above, you must include both the symbolic link dbfile and the
hidden file .dbfile in the file list of the backup class.
If you want to back up all Quick I/O files in a directory, you can simplify the process
by just specifying the directory to be backed up. In this case, both components of
each Quick I/O file will be properly backed up. In general, you should specify
directories to be backed up unless you only want to back up some, but not all files,
in those directories.
Because Veritas NetBackup is integrated with Veritas Storage Foundation, Veritas
NetBackup backs up extent attributes of a Quick I/O file and restores them
accordingly. Quick I/O files can then be backed up and restored as regular files
using Veritas NetBackup, while preserving the Quick I/O file's extent reservation.
Without this feature, restoring the file could cause the loss of contiguous
reservation, which can degrade performance.
When restoring a Quick I/O file, if both the symbolic link and the hidden file
already exist, Veritas NetBackup will restore both components from the backup
image. If either one or both of the two components are missing, Veritas NetBackup
creates or overwrites as needed.
Note: The Oracle backup and restore utility cannot be used to back up and restore
Quick I/O files.
Some back up software may not be able to back up and restore VxFS extent
attributes. See the qio_recreate(1M) online manual page for information on how
to restore missing Quick I/O files.
