Checkpoint Frequency
This field contains the number of data records between check-
points.
Fast Search Mark Frequency
This field contains the number of files between fast search
marks for backups made with DDS tape drives.
Index Size This field contains the size of the index.
Backup Identification Tag
This field is composed of 2 items: the process ID (pid), and the
start time of that process.
Language This field contains the language used to make the backup.
-R path An interrupted full recovery can be continued using this option.
frecover uses the informa-
tion in file path to continue the recovery from where it was interrupted. The only command
line option used by
frecover with this option is
-f. The values in path override all other
options to
frecover. Note also that only full recoveries are restarted with this option,
because no history of include or exclude lists is stored in the restart file. If a partial recovery
(i.e., using the -x option) is interrupted then restarted with this option, frecover continues
recovering where the partial recovery left off, but restores all files on the backup media beyond
this point.
The following options can be used in addition to the option above that selects the desired function:
-c config config specifies the name of a configuration file to be used to alter the behavior of
frecover.
The configuration file allows the user to specify the action to be taken on all errors, the max-
imum number of attempts at resynchronizing on media errors (
-S option), and the action to be
taken on media errors. Each entry of a configuration file consists of an action identifier fol-
lowed by a separator followed by the specified action. Valid action identifiers are
error,
chgvol, and sync. Separators can be either tabs or spaces. In the following sample
configuration file, each time an error is encountered, the script
/var/adm/fbackupfiles/frecovererror
is executed. The script
/var/adm/fbackupfiles/frecoverchgvol
is executed each time the backup media
is to be changed. The maximum number of resynchronization attempts is five.
error /var/adm/fbackupfiles/frecovererror
chgvol /var/adm/fbackupfiles/frecoverchgvol
sync 5
-e
path path is interpreted as a graph to be excluded from the recovery. There is no limit on how
many times the -e option can be specified.
-f device device identifies the backup device to be used instead of the default
/dev/rmt/0m or
/dev/rtape/tape1_BEST
on systems where legacy Device Special Files (DSF) is dis-
abled. If device is
-, frecover reads from standard input. Thus fbackup and frecover
can be used in a pipeline to backup and recover a file system as follows:
fbackup -i /usr -f - | (cd /mnt; frecover -Xrf -)
If more than one output file is specified, frecover uses each one successively and then
repeats in a cyclical pattern. Patterns can be used in the device name in a way similar to file
name expansion as done by sh. The expansion of the pattern results in all matching names
being in the list of devices used. A device on the remote machine can be specified in the form
machine:device. frecover creates a server process, /usr/sbin/rmt, on the remote
machine to access the tape device. If /usr/sbin/rmt does not exist on the remote system,
frecover creates a server process from /etc/rmt on the remote machine to access the
tape device. The pattern matching capability does not apply to remote devices. Only raw
magnetic tapes can be remote devices. The fast search marks capability is not used when
accessing remote DDS devices.
-g graph graph defines a graph file. Graph files are text files and contain the list of file names (graphs)
to be recovered or skipped. Files are recovered using the -i option; so, for example, if the
user wants to recover all of /usr, the graph file contains one entry:
i /usr
