System Requirements for MongoDB

Verify that your environment meets the system requirements.

All Environments

• All instances must run with configuration files in the YAML format.

• If the ports between the master node and the other cluster nodes are blocked, the nodes must connect through a firewall.

Linux Environments

• Database authentication is supported on both Windows and Linux for full backups. Authentication is supported only on Linux for incremental backups.

• The user account that you authenticate with must have one of the following role or roles on the admin database:

  • The root role. This is a superuser role. If you choose to overwrite the database or collection, you must grant the root role to the MongoDB user.

  • A set of roles (backup, restore, clusterMonitor, hostManager). If you do not want to assign the superuser role to the database user, then use these roles.

• Logical Volume Manager (LVM) volume groups must have adequate free space for creating the IntelliSnap snapshots. The default COW cache size is set to 4096 MB or 5% of the volume size, whichever is greater. You can increase the COW cache size.

Replica Set Environments

• Replica sets must have at least one secondary node.

• The Encryption at rest support feature is supported for replica set clusters using local key mechanisms with the same key on all nodes. Additional settings must be configured on the source nodes for the encryption key file to be backed up. The file also needs to be present on the destination clients for the restore operation.

  During in-place restores, the encryption key file is restored to its original location. Existing key files are renamed. During out-of-place restores, the encryption key file is restored to the same path as the path discovered in the destination cluster. If the destination cluster does not have encryption enabled, it is restored to the path where it was in the source cluster.

Sharded Cluster Environments

• The same database user must be created on all the sharded servers and on the config server.

• Each sharded server must be a replica set, and the replica set must have at least one secondary node.

• The Commvault software is not required on the arbiter node.
