RPMCheck yes or no compares the packages installation of the source host with this affa backup host. Sends a message with diff list if not in sync. This check is usefull, if you want have the option to rise the backup server to a production server from a backup.
DiskSpaceWarn strict or normal or risky or none run a disk space check after a job has been completed. With level 'strict' a warning message will be sent, if the available space is less then the size of the just completed backup. With level 'normal'/'risky' the message is sent, if less than 50%/10% of the backup size is still available.
localNice -19...+19 run rsync local process niced.
remoteNice -19...+19 run rsync process on source niced.
Watchdog yes or no when a job is started, affa installs a watchdog script on the source in /etc/cron.d/, which sends a warning message, if the next scheduled job (taken from the TimeSchedule property + 10 minutes) did not run. This guarantees, that you will be notfied even in case of a affa server outage. The watchdog script send a daily reminder message, if the error continues. The next run job replaces the watchdog script with a new trigger time.
ConnectionCheckTimeout seconds before the rsync is started on the remote source host, affa check the ssh conncetion and exits with an error after the configured time, if the host does not response.
rsyncTimeout seconds Rsync exits, if no data is transferred for the configured time. This avoids infinitely hanging in case of a network error.
rsyncCompress yes or no compress the tranferred data. May be useful with slow internet connections. Needs addtional CPU resources on source and backup host.
EmailAddresses name@domain.com,name@domain.com,... comma separated list of mail addresses where the messages should be sent to
preJobCommand
postJobCommand
full path programs (local on the affa server) to be executed before/after a job run. The jobname and type (scheduled, daily etc.) are passed as arguments to the program. The exit code is additionally passed to the post job command program. See /usr/lib/affa/ for sample perl scripts.
RootDir full path where to store the backup archives, Do not use /home/e-smith or /root as these are included in the backup and therefore the rise otpion will not work! Recommended: /var/affa
Debug yes or no set to yes to increase log verbosity
status enabled or disabled with set to disabled, no cron entries will made. You can still run a job manually.
rsync--inplace yes or no set to no, if the rsync versionon the source does not support this option (like rsync on SME6)
