Checkpoints

Note

Groups and projects are synonymous terms. Your {PROJECT-ID} is the same as your project id. For existing groups, your group/project id remains the same. This page uses the more familiar term group when referring to descriptions. The endpoint remains as stated in the document.

This resource allows you to view Checkpoints metadata. You can use checkpoints to create custom snapshots of a cluster at points in time between regular snapshots.

Important

You may use checkpoints for clusters that run MongoDB with Feature Compatibility Version of 4.0 or earlier. Checkpoints were removed from MongoDB instances with FCV of 4.2 or later.

Endpoints

Get All Checkpoints

Get all checkpoints for a cluster.

GET /groups/{PROJECT-ID}/clusters/CLUSTER-ID/checkpoints

Get One Checkpoint

Get a single checkpoint.

GET /groups/{PROJECT-ID}/clusters/CLUSTER-ID/checkpoints/CHECKPOINT-ID

Entity Fields

Name
Type
Description
clusterId
string
Unique identifier of the cluster represented by the checkpoint.
completed
string
Timestamp in ISO 8601 date and time format in UTC for the point-in-time when the checkpoint completed and the balancer restarted.
groupId
string
Unique identifier of the group that owns the checkpoint.
id
string
Unique identifier of the checkpoint.
parts
array of objects
Individual parts that comprise the complete checkpoint. There will be one element for each shard plus one element for the config servers.
parts
.replicaSetName
string
Name of the replica set. Not present for a config server.
parts
.shardName
string
Name of the shard.
parts
.tokenDiscovered
Boolean
Flag that indicates whether the token exists.
parts
.tokenTimestamp
object
Timestamp of an entry in the oplog, as specified by the entry’s ts field. The ts field is a BSON timestamp and has two components: the timestamp, which is the value in seconds since the Unix epoch, and the increment, which is an incrementing ordinal for operations within a given second.
parts
.typeName
string

Type of server represented by the part. Possible values are:

  • REPLICA_SET, which indicates the part is a shard.

  • CONFIG_SERVER

restorable
Boolean
Flag that indicates whether the checkpoint can be used for a restore.
started
string
Timestamp in ISO 8601 date and time format in UTC for the point-in-time when Ops Manager stopped the balancer and began the checkpoint.
timestamp
string
Timestamp in ISO 8601 date and time format in UTC for the point-in-time to which the checkpoint restores data.
