You can use the fts clone command to back up a single read/write DCE LFS fileset; you can use the fts clonesys command to back up multiple read/write DCE LFS filesets at one time. You can combine the options available with the fts clonesys command in different ways to indicate the filesets that are to be backed up; the following list summarizes the possible combinations. To back up
· All filesets in the local cell, specify no options
· All filesets in the local cell with a name beginning with the same character string (for example, sys. or user.), specify the string with the -prefix option
· All filesets on a File Server machine, specify the machine's name with the -server option
· Filesets on a specific aggregate on a File Server machine, specify both the -server and -aggregate options
· Filesets with a certain prefix on a specific File Server machine, specify both the -prefix and -server options
· Filesets with a certain prefix on a specific aggregate on a File Server machine, specify the -prefix, -server, and -aggregate options
You may want to make backup versions of particular filesets every day at the same time. You can issue the fts clonesys or fts clone commands at the console, or you can create a cron entry in the BosConfig file on each File Server machine where you want to back up filesets.
The following example creates a cron process called backupusers in the BosConfig file on the machine named fs3. The process executes every day at 5:30 a.m., making a backup version of every fileset in the cell's filespace that has a name that starts with user. The -localauth option allows the process, which runs unauthenticated, to use the DFS server principal of fs3 to execute the privileged fts clonesys command.
$ bos create /.../abc.com/hosts/fs3 backupusers cron "dcelocal/bin/fts clonesys -prefix user -localauth" 5:30
