-  + 
-dsmc restore "/data/*" /different/location/ -su=yes +  dsmc restore "/data/*" /different/location/ -su=yes 
- ("/" at end is recommended) + 
- ("-su" means do subdirectories"+The "/" at end of the new location is mandatory.

 +  * :!: Please note that performing several restores in a row sometimes pulls in files that were previously marked as unavailable 
 + 
 +==== Delete files from backup and archive ==== 
 + 
 +The commands are: 
 + 
 +  dsmc delete backup ...

 + 
 +  * List restartable restore sessions: 
 + 
 +  dsmc query restore

 +===== Options ===== 
 + 
 +  * Options apparently go at the end of a command. 
 + 
 +  * It looks like using dsmc interactively will wait for tape mounts but otherwise it won't. You can use the //tapeprompt// option: 
 + 
 +<code> 
 +  -tapeprompt=no 
 +</code>
  
-It looks like using dsmc interactively will wait for tape mounts but otherwise it won't. Maybe there's an option to use?+"No" is the default and means TSM will automatically wait for the tape to be mounted. "Yes" means TSM will ask the user whether to wait or not.
  
--tapeprompt=no (default) +  * Specify what to do when trying to restore to an existing file with:
- - means that it will wait +
- - yes means you will be prompted+
  
--replace= +<code>
