Backup of your entire cluster periodically to minimize data inconsistency when a restore is required.

Backing up your data should be a regular process on your cluster to ensure that you do not lose information in the event of a serious hardware or installation failure.

There are a number of methods for performing a backup:

• Using cbbackup

  The cbbackup command enables you to back up a single node, single buckets, or the entire cluster into a flexible backup structure that allows for restoring the data into the same, or different, clusters and buckets. All backups can be performed on a live cluster or node. Using cbbackup is the most flexible and recommended backup tool.

• Using File Copies

  A running or offline cluster can be backed up by copying the files on each of the nodes. With this method, you can only restore to a cluster with an identical configuration.

  Note: Due to the active nature of Couchbase Server it is impossible to create a complete in-time backup and snapshot of the entire cluster. Because data is always being updated and modified, it would be impossible to take an accurate snapshot.
