Record Size This field contains the maximum length in bytes of a data record.
Time This field contains the clock time when
fbackup was started.
Media Use This field contains the number of times the media has been used
for backup. Since the information is actually on the media, this
field will always contain the value 0.
Volume Number This field contains a
# character followed by 3 digits, and
identifies the number of volumes in the backup.
Checkpoint Frequency
This field contains the number of data records between check-
points.
Index Size This field contains the size of the index.
Backup Identification Tag
This field is composed of two items: the process ID (pid) and the
start time of that process.
Language This field contains the language used to make the backup.
-R restart Restart an fbackup session from where it was previously interrupted. The restart file
contains all the information necessary to restart the interrupted session. None of the
-
[ieg0-9] options can be used together with the restart option.
-0-9 This single-digit number is the backup level. Level
0 indicates a full backup. Higher levels
are generally used to perform incremental backups. When doing an incremental backup of
a particular graph at a particular level, the database of past backups is searched to find the
date of the most recent backup of the same graph that was done at a lower level. If no such
entry is found, the beginning of time is assumed. All files in the graph that have been
modified since this date are backed up.
Access Control Lists (ACLs)
If a file has optional ACL entries, the
-A option is required to enable its recovery on a system where the
ACL capability is not present.
EXTERNAL INFLUENCES
Environment Variables
LC_COLLATE determines the order in which files are stored on the backup device and the order of output
by the -I option.
LC_TIME determines the format and contents of date and time strings.
LC_MESSAGES determines the language in which messages are displayed.
If
LC_COLLATE, LC_TIME, and LC_MESSAGES are not all specified in the environment, or if either is
set to the empty string, the value of LANG is used as a default for each unspecified or empty variable. If
LANG is not specified or is set to the empty string, a default of "C" (see lang(5)) is used instead of
LANG.
If any internationalization variable contains an invalid setting,
fbackup behaves as if all internationali-
zation variables are set to "C". See environ (5).
International Code Set Support
Single- and multi-byte character code sets are supported.
RETURN VALUE
fbackup returns one of the following values:
0 upon normal completion.
1 if it is interrupted but allowed to save its state for possible restart.
2 if any error conditions prevent the session from completing.
4 if any warning conditions are encountered.
If warnings occur, the operator should check the fbackup logs to verify the sanity of the backup.
EXAMPLES
In the following two examples, assume the graph of interest specifies all of /usr except /usr/lib (as
described for the -g option above).
The first example is a simple case where a full backup is done but the database file is not updated. This
can be invoked as follows:
