You can set the virtualmountpoint and domain options without specifying all the AFS volume mount points or all the DFS fileset mount points. For example, rather than listing all AFS or DFS user home directories, specify their parent directory (/afs/sanjose.ibm.com/u or /.../sanjose.ibm.com/fs/u) as a virtual mount point. See the examples below. For AFS:
virtualmountpoint /afs/sanjose.ibm.com/u
Set the afsbackupmntpnt option to no. The client program crosses the AFS volume mount points in the /afs/sanjose.ibm.com/u directory, then backs up all the mounted AFS user volumes. For example, enter the following line in the client system options file:
afsbackupmntpnt no
Attention: Use this AFS setup with caution because it backs up all volumes mounted below /afs/sanjose.ibm.com/u. When you create AFS mount points, you expose the backup operation to potential cyclic mount points. If you link to the root of a foreign AFS cell, you also expose the backup operation to potential mount points.
For DFS:
virtualmountpoint /.../sanjose.ibm.com/fs/u
Set the dfsbackupmntpnt option to no. The client program crosses the DFS fileset mount points in the /.../sanjose.ibm.com/fs/u directory. The client program then backs up all the mounted DFS user filesets. For example, enter the following line in the client system options file:
dfsbackupmntpnt no
Attention: Use this DFS setup with caution because it backs up all filesets mounted below /.../sanjose.ibm.com/fs/u. When you create AFS mount points, you expose the backup operation to potential cyclic mount points. If you link to the root of a foreign DFS cell, you also expose the backup operation to potential mount points.
You can set domain options in your client user options file to include the virtual mount point in your default client domain. See the examples below.
For AFS:
domain /afs/sanjose.ibm.com/uFor DFS:
domain /.../sanjose.ibm.com/fs/u/alice domain /.../sanjose.ibm.com/fs/u/bob domain /.../sanjose.ibm.com/fs/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).
