the date can be constructed with strftime substitutions (see below). My thoughts on a solution would be: $DOM/%G-$DOM and check tar+gzip as compression format.
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.
%T The time in 24-hour notation (%H:%M:%S).
%u The day of the week as a decimal, range 1 to 7,
Monday being 1. See also %w.
%U The week number of the current year as a decimal
number, range 00 to 53, starting with the first
Sunday as the first day of week 01. See also %V and
%W.
%V The ISO 8601:1988 week number of the current year
as a decimal number, range 01 to 53, where week 1
is the first week that has at least 4 days in the
current year, and with Monday as the first day of
the week. See also %U and %W.
%w The day of the week as a decimal, range 0 to 6,
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
locale without the date.
%y The year as a decimal number without a century
(range 00 to 99).
%Y The year as a decimal number including the century.
%z The time-zone as hour offset from GMT. Required to
emit RFC822-conformant dates (using "%a, %d %b %Y
%H:%M:%S %z").
%Z The time zone or name or abbreviation.
%% A literal '%' character.
After looking at this, I realized the crux of the issue… where do I set the File Name? I don’t see that option in the UI anywhere. (I’m on GPL, if that matters.) I have the option checked off, but there’s no where to enter the variables.
Hm, that is an option, although it’s an added layer of complication. I’d prefer if it was an integrated part of the system, if possible. I’ll open a Feature Request.
