### minimum-items < INTEGER >
Specifies the minimum number of backup files/dirs that must be present before rotating can happen. Should be an integer.
This option doesn't specify how much to rotate on its own, but when rotation is possible. It should probably be used with maximum-age or something other than maximum-items.
For example, when the *minimum-items* value is set to 5, and *target-type* is *file*, the program will not rotate any files until there are at least 5 in the target directory.
### maximum-items < INTEGER > ### maximum-items < INTEGER >
Specifies the maximum number of backup files/dirs that are allowed in a path before rotating will happen. Should be an integer. Specifies the maximum number of backup files/dirs that are allowed in a path before rotating will happen. Should be an integer.
For example, when the *maximum-items* value is set to 5, and *target-type* is *file*, the program will not rotate any files until there are at least 5 in the target directory. For example, when the *maximum-items* value is set to 500, and *target-type* is *file*, the program will not rotate any files until there are at least 500 in the target directory.
### maximum-age < INTEGER >
Specifies the maximum age (in days) of backup files/dirs that are allowed in a path before rotating will happen. Should be an integer.
For example, when the *maximum-age* value is set to 30, and *target-type* is *file*, the program will not rotate any files that are newer than 30 days.
