Use the exclude.fs option to exclude /afs or /... as a file space. Add Tivoli Storage Manager virtual mount point definitions in your client system options (dsm.sys) file for the portions of AFS or DFS that you want to back up.
Specify a Tivoli Storage Manager virtual mount point for every AFS volume or DFS fileset that you want to back up. Set afsbackupmntpnt to yes (the default) or dfsbackupmntpnt to yes (the default). For example, to schedule incremental backups of all AFS volumes, define a virtual mount point for each directory that begins a user volume. See the example below.
virtualmountpoint /afs/sanjose.ibm.com/u/alice virtualmountpoint /afs/sanjose.ibm.com/u/bob virtualmountpoint /afs/sanjose.ibm.com/u/charlie
To schedule incremental backups of all DFS volumes, define a virtual mount point for each directory that begins a user volume. See the example below.
virtualmountpoint /.../sanjose.ibm.com/fs/u/alice virtualmountpoint /.../sanjose.ibm.com/fs/u/bob virtualmountpoint /.../sanjose.ibm.com/fs/u/charlie
Set corresponding domain options in your client user options (dsm.opt) file to include the virtual mount points in your default client domain. See the example below.
domain /afs/sanjose.ibm.com/u/alice domain /afs/sanjose.ibm.com/u/bob domain /afs/sanjose.ibm.com/u/charlie
You can then schedule a daily incremental backup using the dsmcafs incremental or dsmcdfs incremental command through a crontab job (or any other scheduling tool).
