    /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).

    %I The hour as a decimal number using a 12-hour clock
    (range 01 to 12).

    %j The day of the year as a decimal number (range 001
    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.)

    %l The hour (12-hour clock) as a decimal number (range
    1 to 12); single digits are preceded by a blank.
    (See also %I.)

    %m The month as a decimal number (range 01 to 12).

    %M The minute as a decimal number (range 00 to 59).

    %n A newline character.

    %O Modifier: use alternative format, see below.

    %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'.

    %R The time in 24-hour notation (%H:%M). For a
    version including the seconds, see %T below.

    %s The number of seconds since the Epoch, i.e., since
    1970-01-01 00:00:00 UTC.

    %S The second as a decimal number (range 00 to 61).

    %t A tab character.

    Sunday being 0. See also %u.

    %W The week number of the current year as a decimal
    number, range 00 to 53, starting with the first
    Monday as the first day of week 01.

    %x The preferred date representation for the current
    locale without the time.

    %X The preferred time representation for the current
