PROGRAM="$SUBPROGRAM-batch" # Batch program to run osync / obackup instances sequentially and rerun failed ones
AUTHOR="(L) 2013-2016 by Orsiris de Jong"

PROGRAM_BUILD=2016081701
## Runs an osync /obackup instance for every conf file found
## If an instance fails, run it again if time permits
## Configuration file path. The path where all the osync / obackup conf files are, usually /etc/osync or /etc/obackup
CONF_FILE_PATH=/etc/$SUBPROGRAM
## If maximum execution time is not reached, failed instances will be rerun. Max exec time is in seconds. Example is set to 10 hours.
MAX_EXECUTION_TIME=36000
## Specifies the number of total runs an instance may get
MAX_RUNS=3
## Log file path
