You should backup your installation directory and the corresponding database. We are doing this with a simple batch-script twice a day, you may want to use something like this in a .bat file:
C:\Programme\7-Zip\7z.exe a -rbdy CRM_backup.7z d:\pathToMyCRM
"C:\Programme\MariaDB 5.5\bin\mysqldump.exe" --user=yourSQLuser --password="yourPassword" yourDatabaseName > sqldump.sql
The first line creates a compressed backup of your installation directory (install 7zip first) named CRM_backup.7z, the second line creates a backup of your database named sqldump.sql. With these two files you are able to install your CRM with current data wherever you want. Adjust path names and user credentials to make this work.
