As noted in the Frequently Asked Questions, Client Service Tracker is a Microsoft Access database, so to back it up, you make a copy of the database file and store it in a secure place on another computer or on the Internet. Then if there is a crash and you lose Client Service Tracker, you can restore the database file from the copy you made.
There are several ways to make a backup copy of a file, either manually or using a software or service to automate it. A very easy way to set this up is to use an automated service that will back up files from your computer and store them securely on the Internet. Possible choices include Carbonite and iDrive. A review of many online backup services can be found here: 21 Online Backup Services Reviewed. The Social Work Software office uses iDrive and has been very satisfied with it. You can set iDrive to back up continuously. The basic service is free and gives you 5 gigabytes of storage, which is more than enough if all you are doing is backing up Client Service Tracker. Other online backup services may also work well for you.
What should you back up? If you use the setup file to install Client Service Tracker to its default location and you did not make any other location changes (as discussed below), then look in your “Documents” folder for a subfolder. Back up all of the folder named “Client Service Tracker” or “Client Service Tracker 9.”
If you have put Client Service Tracker on a network and have “split the database” (as described in Steps for Putting Client Service Tracker on a Network), then if the back end database is an Access database, back it up (it probably has a name ending with “_be”). If the back end database is a Microsoft SQL Server database, then it will have its own backup processes.
