Description

Operation path

If you are backing up a drive, specifies one or more paths of the directories to be backed up. If you are backing up Microsoft Exchange Server components, specifies the component and the server as {directory service server /information store server}. Server is the name of the server you are backing up, preceded by two backslashes. Directory service indicates that you are backing up the directory, and information store indicates that you are backing up the information store.

/a

Causes backup sets to be added after the last backup set on the tape. When /a is not specified, the program reuses the tape and replaces previous data. When more than one drive is specified but /a is not, the program overwrites the contents of the tape with the information from the first drive selected and then appends the backup sets for the remaining drives.

/v

Verifies the operation.

/v /r

Restricts access.

/d "text"

Specifies a description of the backup contents.

/b

Specifies that the local registry be backed up.

/hc:on or /hc:off

Specifies that hardware compression is on or off.

/t {option}

Specifies the backup type. Option can be one of the following: normal, copy, incremental, differential, or daily.

Normal

All selected files or Microsoft Exchange Server components are backed up and marked as such on the disk.

Copy

All selected files or Microsoft Exchange Server components are backed up, but they are not marked as such on the disk.

Incremental

Among the selected files or Microsoft Exchange Server components, only those that have been modified are backed up and marked as such on the disk.

Differential

The selected files or Microsoft Exchange Server components that have been modified are backed up, but are not marked as such on the disk.

Daily

Among the selected files, only those that have been modified the same day are backed up, but they are not marked as such on the disk. This can be useful if you want to take work home and need a quick way to select the files that you worked on that day. This option is not available when backing up Microsoft Exchange Server components.

/l "file name"

Specifies the file name for the backup log.

/e

Specifies that the backup log include exceptions only.

/tape:{n}

Specifies the tape drive to which the files should be backed up. N is a number from zero to nine that corresponds to the tape drive number listed in the registry.
