MongoDB Cloud Manager

Technology

Mongobackup is cloud backup system that works with platforms such as N2WS and is able to perform incremental backup mongodb. This tool is external and used via a software to begin backups and storing the backups on the file system; the compression features includes lz4 algorithm

Full backup is done by performing a file system copy of the dbPath and partial oplog dump is used for incremental backup.

Features

Mongo DB can perform full incremental backups rather than just a standard backup. A time can be set for a point in time restoration when wanting to restore data to a device. The backup can be conducted daily, weekly or even monthly, according to when a backup is required.

Another feature is that a partial dump of the oplogcan be made and this would only be applied to the last existing backup dumped. The backups can be secured by using fsyncLock / fsyncUnlock(https://docs.mongodb.org/manual/reference/method/db.fsyncLock/) however is important to avoid interfering with the primary node when using this function.

The MongoDB cloud manager is able to back up and monitor services within MongoDB such as incremental backups. This function also supports back-ups and restoring duplicates of data from sharded clusters via the user interface.

This manager also supports the process of restoring MongoDB deployments via backing up initially. It is able to consistently back up from replicas via the oplog data log that is based on the MongoDB deployment.

Using Ops Manager

Ops manager coexists with MongoDB followers that are able to install the replica software from the main cloud manager via their own device – ops manager is similar to MongoDB in its functions and is an on-premise solution that works well overall. Enterprise advanced subscribers can also use the system easily. There is also the option to create a backup through the MongoDB by creating a reformed copy of data.

The snapshots that support point in time shots can be used to create backups through MongoDB systems and can be processed at specific time scales for consistency.

The snapshots on the file system are essentially used as a volume manager function but directly related to MongoDB manager – when the file system snap shots are available the system will take a shot of the volume as a guidance to use a baseline for a backup of data, however the technicality of the snapshots is varied on the storage underneath.  It is important to have journaling available and enabled to capture a valid snapshot of Mongod functioning, the journal works in a similar way to volume and other data file with MongoDB manager for cloud backups and restoration.
