Backup Utility in C#

A utility to backup directories and stick a datestamp on the folder, and remove folders older than N days, where N is configurable.

Sample Image - backup.gif


During a development project, I realized I needed something to backup my solutions every night, and be tagged with a date stamp. I looked around the Net for some DOS utilities but none really fitted the bill as far as what I was looking for. Eventually, I decided to just code it. Turned out to be super simple in C#.


My goal was to backup my solution from a source folder (e.g. C:\Data) to a backup folder (e.g. C:\Backup\Data_080403). I also wanted to only keep N number of days of backups and not let my backup folder grow infinitely. So, for instance, I wanted to keep 30 days worth of backups at most. So, whenever, any files older than 30 days were discovered, I wanted the system to delete them automatically.


I used the System.IO's Directory and DirectoryInfo classes to create folders, delete folders, and wrote a method to recursively copy folders from one location to the next. I utilized the DirectoryInfo class to figure out how old a given folder was, in order to delete it.

For single home developer's not sharing code with other's this may be considered. Otherwise there is PVCS systems like MS SourceSafe keeping track of versions and releases.

How about creating an old fashion DOS command file instead? Smile | :)


md c:\mybackup\%1
xcopy c:\mysourcecode\*.* c:\mybackup\%1\*.* /E

%1 parameter can be date or day number or whatever. There is also possible to get a date inside the command file and running it without parameter, but this is more flexible. Error checking can be added if needed, so the parameter is right.

No need for coding, xcopy does the recursive job for you.
