When you use a command prompt or a batch file to run the NTBackup utility, and you include command-line parameters with the ntbackup
command, NTBackup does not run as expected.
This problem occurs if you use a slash character and a letter in the following combinations as part of a parameter for a switch:
NTBackup reads each of these character combinations as if it were another switch itself (instead of just part of a switch parameter).
For example, in the following command syntax, the parameter that is used with the /d
switch contains the "/r" character combination. This character combination is read by NTBackup as the /r
switch instead of as part of the /d
ntbackup backup "@d:\backup.bks" /j "test backup job" /f "d:\backup.bkf" /d "backup set label /r" /a /v:yes /m copy /hc:off
If this command were to include the /r
switch in the syntax, this problem would not occur. For example, in the following command syntax, the /d
parameter still contains the "/r" character combination. However, because the /r
switch is also clearly stated in the syntax, the problem does not occur:
ntbackup backup "@d:\backup.bks" /j "test backup job" /f "d:\backup.bkf" /d "backup set label /r" /a /v:yes /r:no /m copy /hc:off
