The mover is a utility that runs periodically to move files off the cache disk and onto parity-protected data disk(s). If Mover logging is enabled, the mover will record all its activity to the system log.
By default the mover is scheduled to run every day at 3:40AM. This may be changed by defining your own Mover schedule string in crontab format.
Our crontab format is roughly similar to that used by vixiecron. Individual fields may contain a time, a time range, a time range with a skip factor, a symbolic range for the day of week and month in year, and additional subranges delimited with commas. If you specify both a day in the month and a day of week, it will be interpreted as the Nth such day in the month.

# run at 4:00 am on January 1st 0 4 1 jan *
To request the last Monday, etc. in a month, ask for the "5th" one. This will always match the last Monday, etc., even if there are only four Mondays in the month:
# run at 11 am on the first and last Mon, Tue, Wed of each month 0 11 1,5 * mon-wed
When the fourth Monday in a month is the last, it will match against both the "4th" and the "5th" (it will only run once if both are specified).
