# FTB Backups 2 To change how frequently the FTB Backups 2 mod creates a backup, navigate to the Files page on the panel and open the config folder, in there you will find a file named **ftbbackups2.json** or **ftbbackups2.json5**, double click this file to open it. With the file opened, find the option named `"backup_cron"` this will be set to something similar to `"0 */30 * * * ?"` The format used for this is seconds, minutes, hours, day of month, month, day of week. Examples of common configuration options are:
ExpressionDescription
0 \*/30 \* \* \* ?Every 30 minutes at 0 seconds
0 0 \*/1 \* \* ?Every hour at 0 minutes and 0 seconds
0 0 \*/2 \* \* ?Every 2 hours at 0 minutes and 0 seconds
0 0 \*/4 \* \* ?Every 4 hours at 0 minutes and 0 seconds
0 0 \*/6 \* \* ?Every 6 hours at 0 minutes and 0 seconds
##### Special characters Credit to http://www.quartz-scheduler.org/documentation/quartz-2.3.0/tutorials/crontrigger.html - **\*** (*“all values”*) - used to select all values within a field. For example, “**\***” in the minute field means *“every minute”*. - **?** (*“no specific value”*) - useful when you need to specify something in one of the two fields in which the character is allowed, but not the other. For example, if I want my trigger to fire on a particular day of the month (say, the 10th), but don’t care what day of the week that happens to be, I would put “10” in the day-of-month field, and “?” in the day-of-week field. See the examples below for clarification. - **-** - used to specify ranges. For example, “10-12” in the hour field means *“the hours 10, 11 and 12”*. - **,** - used to specify additional values. For example, “MON,WED,FRI” in the day-of-week field means *“the days Monday, Wednesday, and Friday”*. - **/** - used to specify increments. For example, “0/15” in the seconds field means *“the seconds 0, 15, 30, and 45”*. And “5/15” in the seconds field means *“the seconds 5, 20, 35, and 50”*. You can also specify ‘/’ after the ‘**’ character - in this case ‘**’ is equivalent to having ‘0’ before the ‘/’. ‘1/3’ in the day-of-month field means *“fire every 3 days starting on the first day of the month”*. - **L** (*“last”*) - has different meaning in each of the two fields in which it is allowed. For example, the value “L” in the day-of-month field means *“the last day of the month”* - day 31 for January, day 28 for February on non-leap years. If used in the day-of-week field by itself, it simply means “7” or “SAT”. But if used in the day-of-week field after another value, it means *“the last xxx day of the month”* - for example “6L” means *“the last friday of the month”*. You can also specify an offset from the last day of the month, such as “L-3” which would mean the third-to-last day of the calendar month. *When using the ‘L’ option, it is important not to specify lists, or ranges of values, as you’ll get confusing/unexpected results.* - **W** (*“weekday”*) - used to specify the weekday (Monday-Friday) nearest the given day. As an example, if you were to specify “15W” as the value for the day-of-month field, the meaning is: *“the nearest weekday to the 15th of the month”*. So if the 15th is a Saturday, the trigger will fire on Friday the 14th. If the 15th is a Sunday, the trigger will fire on Monday the 16th. If the 15th is a Tuesday, then it will fire on Tuesday the 15th. However if you specify “1W” as the value for day-of-month, and the 1st is a Saturday, the trigger will fire on Monday the 3rd, as it will not ‘jump’ over the boundary of a month’s days. The ‘W’ character can only be specified when the day-of-month is a single day, not a range or list of days. > The 'L' and 'W' characters can also be combined in the day-of-month field to yield 'LW', which translates to \*"last weekday of the month"\*. - **\#** - used to specify “the nth” XXX day of the month. For example, the value of “6#3” in the day-of-week field means *“the third Friday of the month”* (day 6 = Friday and “#3” = the 3rd one in the month). Other examples: “2#1” = the first Monday of the month and “4#5” = the fifth Wednesday of the month. Note that if you specify “#5” and there is not 5 of the given day-of-week in the month, then no firing will occur that month. > The legal characters and the names of months and days of the week are not case sensitive. MON is the same as mon.
