You have Cobian Backup installed and want to setup a weekly backup.
You will need a dedicated USB disk attached to the PC running Cobian Backup.
Before proceeding, let’s ensure it’s obvious what the USB disk is for. Label the disk as “Cobian Backup” and then create a directory CobianBackup. We’ll store our backups there.
Now, let’s define our backup job. We will be running a Full backup job every Friday and a Differential backup job every other day. We’ll keep 2 Full backups and 14 Differential backups at any point in time.
Setup the Full Backup Job
- Start the Cobian Backup interface. You will probably see that there are no Tasks (backup jobs).
- Click the Create New Task icon.
- We’ll create a new job named FULL. Note that the Backup Type is Differential. Also note that we are leaving “Use Volume Shadow Copy” enabled. On system older systems, VSS may be partially broken and you may end up disabling this option. (Which may even be why you are using Cobian instead of a BMR backup product.)
- Click on Files.
- For Source, which is what you are backing up, add your files or directories. If you have several directories you want to individually backup, using Add->Manual option is easier or you can drag&drop from Explorer. Also, if you have some subdirectories you want to EXCLUDE, we will get to that in a following step. For this example, I’m going to backup the entire E: of a remote server.
- For Destination, you’ll want to choose the CobianBackup directory on the USB disk.
- Click on Schedule and for Schedule Type choose Daily and set the Time to 10:00:00 PM.
- Click on Dynamics. Here is where you define when the Full backup is run and when the Differentials are run. Set 2 Full Copies to be kept, 14 Diffs, and set the Fixed Day for full backups to the best date, which is Friday in this example.
- Now click on Archive. Be wary of this option. If you enable Zip Compression note that:
- Click on Filter. Here is where you exclude files or directories that should not be backed-up. We’re fine for now, but keep this option in mind.
- Click Ok.
