/puclic_html/%Y-%m-%d-%H-%M 表示按日期在public_html目录下生成备份,%d, %m, %Y 表示日,月,年。更详细的介绍看下面:

Do strftime style time substitutions on file or directory name

If this box is checked, codes like %d, %m, %Y and %u can be used in the backup destination filename. These will be replaced with the day, month, year and day of the week respectively when the backup is performed. This is useful if you want to save a different backup every day, so that you can roll a server back to a previous date.

Some of the other codes that can be used are :


 %a     The abbreviated weekday name according to the  cur
        rent locale.

 %A     The  full  weekday  name  according  to the current
        locale.

 %b     The abbreviated month name according to the current
        locale.

 %B     The  full  month  name  according  to  the  current
        locale.

 %c     The preferred date and time representation for  the
        current locale.

 %C     The century number (year/100) as a 2-digit integer.

 %d     The day of the month as a decimal number (range  01
        to 31).

 %e     Like  %d, the day of the month as a decimal number,
        but a leading zero is replaced by a space.

 %E     Modifier: use alternative format, see below.

 %G     The ISO 8601 year with century as a decimal number.
        The 4-digit year corresponding to the ISO week num
        ber (see %V).  This has the same format  and  value
        as  %y,  except that if the ISO week number belongs
        to the previous or next year,  that  year  is  used
        instead.

 %g     Like  %G, but without century, i.e., with a 2-digit
        year (00-99).

 %h     Equivalent to %b.

 %H     The hour as a decimal number using a 24-hour  clock
        (range 00 to 23).

        to 366).

 %k     The hour (24-hour clock) as a decimal number (range
        0 to 23); single digits are preceded  by  a  blank.
        (See also %H.)

        1 to 12); single digits are preceded  by  a  blank.

 %p     Either  `AM'  or  `PM'  according to the given time
        value, or the corresponding strings for the current
        locale.   Noon  is  treated as `pm' and midnight as
        `am'.

 %P     Like %p but in lowercase: `am' or `pm' or a  corre
        sponding string for the current locale.

 %r     The  time  in  a.m. or p.m. notation.  In the POSIX
        locale this is equivalent to `%I:%M:%S %p'.

        version including the seconds, see %T below.
