Prerequisites for Adding a Mac to BDRSuite
KB ID: 115208
Prerequisites
1. User Account with Root Privileges:
Ensure that the user account you intend to use for adding the Mac has root privileges. If you plan to use a non-root account, ensure you have access to the root password.
2. User Account Credentials:
You can provide user account credentials using either of the following methods:
i) Mac Account Option:
You can directly connect to the Mac using the username and password of the specified user account.
ii) Mac Private Key Option:
You can connect to the Mac using the Identity/Pubkey authentication method. If you have already generated a public-private key pair, provide the username, private key, and passphrase (if applicable) to save the Mac credentials. Alternatively, follow the steps below to generate the public-private key pair.
Key Generation Steps:
Step 1: Generate a pair of keys - a public key and a private key using the following command:
ssh-keygen -t rsa
Step 2: Specify the location and filename in the format .ppk to save the key.
Example: /home/key.ppk
Step 3: Enter a passphrase or leave it empty. The private key can be protected with a passphrase.
Step 4: The private key (.ppk) and public key (.pub) will be saved to the specified location and file.
Example:
Your identification has been saved in /home/key.ppk
Your public key has been saved in /home/key.ppk.pub
Step 5: The public key must be placed in a special authorized_keys file containing a list of public keys on the backup host. Use the following command to copy the public key and then paste it into the following file location: /var/root/.ssh/authorized_keys.
xclip -sel clip < public key location
Example: `xclip -sel clip < ~/.ssh/id_rsa.pub`
Step 6: Copy the Private Key file to the backup server using FTP tools. You should now have the Public key on the Mac and the Private key on the backup server.
3. Ports:
Ensure that the SSH Port is open, allowing remote access to the machine. The default SSH port is 22. If you are running the SSH server on a different port, ensure that the port is accessible.
BDR for Mac installed on the backup host uses port 42005 to communicate with the backup server. Ensure that your firewall rules allow port 42005 to be open for communication.
4. Internet Connection:
Ensure that the backup host (Mac) has internet access.
5. Supported Operating Systems:
Supported Mac operating systems include:
Mac Intel Based (64-bit)
MacOS Mojave 10.14 & above
Mac Arm Based (64-bit):
MacOS Big Sur 11 & above
6. System Requirements:
Ensure that the target Mac machine meets the following minimum system requirements:
- Memory: Minimum of 2 GB
- CPU: Minimum of Dual-Core Processor
By ensuring these prerequisites are met, you can seamlessly integrate your Mac into the BDRSuite, facilitating efficient backup and data protection.
