Possible values: yes or noDon’t back up this filesystem.Create an index of files backed up.Encrypt the data sent between the server and client.Maximum number of dumps to run at the same time.Maximum number of days for a promotion. Set to 0 for no promotion. Setto 1 or 2 if the disk is overpromoted.Priority level used if there is no tape to write to. Backups are performeduntil holding disks are full, using the priority to determine which filesystemsto back up first. Possible values: low, medium, high.Whether to use dump or tar.Record backup in time-stamp-database (/etc/dumpdates for dump and/var/lib/amanda/gnutar-lists/ directory for GNU tar).Skip the disk when a level 0 is due.Skip the disk when a level 0 is not due.Amount of time to delay the start of the dump.Dump strategy from one of the following:standard: Default strategynofull: Level 1 dumps every timeskip: Skip all dumpsincronly: Incremental backups onlyAfter defining dumptypes, define the clients to be backed up in the /etc/amanda//disklist (/etc/amanda/DailySet1/disklist in our example) file on theAmanda server, one client on each line in the following format: Replace with the hostname or IP address of the client. If a hostname is used,the server must be able to resolve it to an IP address. Replace with a disk namesuch as sda, a device name such as /dev/sda, or a logical name such as /etc to back up.Replace with a dumptype name as defined in amanda.conf on the server.10To allow the Amanda server access to the client, use the .amandahosts file in the homedirectory of the amanda user on each client, even if the client is also the server.
