Getting Started 

Setting up Comet Server 

Once you have downloaded and installed the Comet Server, you will be presented with the Service Manager app and the setup wizard.

1. Server Activation 

To validate your Comet Enterprise Server, please enter your account details.

Alternatively you can enter a serial number. To generate serials from, log in to the Dashboard, then click the "My Servers" link in the top menu, then click the "Add Server" button.

2. Web Interface 

Comet Server is accessed via a web interface. From here you can configure access to the Server Web Interface. Please note the addresses in the drop down for the Server Interface. You can also configure SSL from this screen. Use a free, automatically-renewing SSL certificate with the 'Automatic' option that integrates with Let's Encrypt.

3. Admin accounts 

Configure administrative account access to your Comet Server. We strongly suggest changing the password of the admin user.

4. Customer Data Storage 

From this screen you can select the location where your Comet server will backup data to.

5. Wizard Complete 

You have now setup the basic elements of your Comet Server to run a backup. Press 'finish' and your Comet server will start and the Server Interface will be available at the addresses in the drop-down of step 2.

6. Enterprise Server Login 

After navigating to the address of your Comet server in a browser, you will be able to login the server.

7. Add a User 

From the quick actions menu, select "Add User". This allows you to create a new user/customer that can run backups.

During this process, you can choose if you want to be able to reset their password; the default storage vault they will back up to; and if they will be part of a policy group. You can configure these additional options at a later date if you wish.

9. Download and install the Comet Backup client 

Using the quick actions menu, you can download the Comet Backup client and install it on the device you wish to backup.

10. Log into the Comet Backup client 

Once you have installed the Comet Backup client, you can login with the user details you created to setup a backup start by selecting '+ Add Protected Item' from here simply follow the short wizard to create a backup. Upon completing this you can run the backup or leave it to run on schedule if you created one.

That covers the basics of setting up your Comet Enterprise server to run a backup.

Setting up Comet client 

For testing, evaluation, and training purposes, we would suggest that you use separate machines for the server and the user device. This will help avoid confusion, as some processes have similar names, and can be easily mixed up.

Once you have configured your Comet server and installed the Comet client application; log into the client and you will be able to configure protected items & storage locations.

1. Adding Storage Vault 

Set up a storage vault in the "Account" tab by clicking "+ Add Storage Vault". Now either choose your request-able storage vault you have configured on your Comet server or select Custom if you want to have a unique storage vault for this client. The custom option will allow you to set up local path backups or to have the client send data directly to your cloud storage and more.

2. Backing up (Files and Folders) 

Go to the "Backup" tab and click "+ Add Protected Item", name this protected item and choose the Files and Folders backup type.

Select items to be backed up 

Add the items you would like to be backed up. You can exclude a range of files from the backup job. An exclusion filter checks whether to exclude each file from backup, using either a glob pattern or a regular expression (regex). There is no limit to the number of exclusion filters you can add to a single Protected Item.

Take filesystem snapshot 

On Windows, the "Take filesystem snapshot" option creates a VSS snapshot. This enables Comet to backup files that are currently in-use. It also provides disk-wide "crash-consistency", as all files for backup will originate from the precisely same timestamp.


You can register additional commands to run before- or after any backup job. For maximum flexibility, commands can be registered

for a Protected Item (e.g. to dump a database), or for a Storage Vault (e.g. to perform custom network authentication), or for a Schedule (e.g. to shut down the computer afterward). During a backup job, the commands are run in this order: Schedule Before, Protected Item Before, Storage Vault Before, Backup, Storage Vault After, Protected Item After, Schedule After.

Shell built-ins can be used as part of the command execution - the specified command is passed to either cmd.exe or /bin/sh as appropriate for your operating system.


Comet can run backup jobs automatically on a schedule. It is strongly recommended to automate your backups on a regular schedule. When a schedule is due to run, the backup job will run automatically to the selected Storage Vault.

You can also configure advanced backup runtime options.


You can configure a retention policy to apply when backing up this Protected Item to a specific Storage Vault. If no policy is configured for a specific Storage Vault, the default retention policy for the Storage Vault will apply.

Policy Groups 

On the Comet server, an administrator can create and assign policies to each account to be able restrict certain functionalities on the Comet client.
