windows default iconBACKUP9 Publisher's description

The BACKUP9.EXE utility will maintain a number of backups (9 by default) of a file.

Gammadyne Corporation offers the following DOS command line programs which you may download and use freely.


* These programs run on all versions of Windows since 95.

* These programs do not have a graphical user interface. They are meant to run from a command line (DOS prompt), batch file, or shortcut. You should keep your command line programs in a directory on your hard drive, preferably one in the PATH. For Windows 95/98/ME, we recommend "c:windowscommand". For Windows NT4/2000/XP/2003/Vista/2008/7 we recommend "c:windowssystem32".

The BACKUP9.EXE utility will maintain a number of backups (9 by default) of a file. For example, this command:

backup9.exe c:bazfoo.bar

Will generate these backup files:


Where foo.bar.bk1 is the most recent backup, foo.bar.bk2 is the next most recent backup, et cetra. Please note that this assumes that backup9 was called 9 times, and the original file changed each time.


backup9 [/a] [/e] [/i] [/l#] [/m] [/nologo] [/q] [/s] [/v] filespec [target]

Where filespec is a specification of the file(s) that should be backed up, and target is the directory where the backup files should be created.

/a Always perform backup, even if no change since last backup.
/e Replace the source file's extension instead of appending.
/i Ignore errors in the file specification.
/l Number of backup levels, from 1 to 999 (defaults to 9).
/m Maintain the directory structure. This is only applicable with the /s switch and a target directory.
/nologo Suppress logo banner.
/q Quiet mode - no banner or operation status.
/s Recursively enter subdirectories.
/v Verbose mode.


* The filespec can contain the wildcard characters, the asterisk (*) and the question mark (?). It can also include multiple files separated by semi-colons.
* If the target directory does not already exist, it will be created. If no target directory is specified, the backup files are created in the same directory as the source file.
* If either the filespec or target parameter contains spaces, it should be enclosed in quotes.
* No backup is made if the file has not changed since the last backup.
* If a file is locked, backup9 will retry up to 10 times over a one second period. This is helpful for files that are sometimes briefly locked, like a database.
* Pressing the Escape key will interrupt the operation.
