The server Commands
time-based incremental archive (only files that were changed during
a specified time range will be archived).
A time range is made up of six different fields and each field must
contain two digits. The format is:
[yy[mm[dd[hh]]]]mm[ss]
where yy is the last two digits of the year, the first mm is the month
(from 01 to 12), dd is the day of the month (from 01 to 31), hh is the
hour of the day (from 00 to 23), the second mm is the minute (from 00
to 59), and ss is seconds (from 00 to 59). The minute field mm is
required, while the other fields are optional, and must be added in
the following order: hh, dd, mm, yy. The ss field may be added
independently of the other fields. Time ranges are relative to the
current time, so -T 1234/cm selects all files with a modification or
inode change time of 12:34 PM today or later. Multiple -T time range
can be supplied, and checking stops with the first match.
-X
When traversing the file hierarchy specified by a pathname, does not
allow descending into directories that have a different device ID. See
the st_dev field as described in stat 2 for more information about
device IDs.
-Y
Ignores files that have a less recent file inode change time than a
pre-existing file, or archive member with the same name.
Note: This option is the same as the -D option, except that the inode change
time is checked using the pathname created after all the file name
modifications have completed.
-Z
Ignores files that are older (having a less recent file modification
time) than a pre-existing file, or archive member with the same name.
Note: This option is the same as the -u option, except that the modification
time is checked using the pathname created after all the file name
modifications have completed.
The options that operate on the names of files or archive members (-c,
-i, -n, -s, -u, -v, -D, -T, -Y, and -Z) interact as follows.
When extracting files during a read operation, archive members are
selected, based only on the user-specified pattern operands as modified
