Snapshots

This page displays detailed information about backup snapshots, including snapshot history and performance metadata. Use the snapshot details to monitor backup performance, analyze transfer speeds, and troubleshoot completion issues.

Note

Snapshot metadata features are available in Ops Manager 8.0+, 7.0.2, and 6.0.23 or later versions.

View Snapshot Details

The Snapshots page displays a table of recent snapshots with basic information including snapshot timestamps and completion status.

To view detailed snapshot metadata, click the json button next to any snapshot entry. The system displays comprehensive metadata about the snapshot operation in JSON format, including transfer speed, duration metrics, file counts, and storage size information.

Snapshot Metadata Fields

When you click the json button for a snapshot, Ops Manager displays detailed metadata in JSON format. The following table describes the metadata fields available in the Admin interface:

Field	Type	Description
`numFiles`	number	Total number of files included in the snapshot.
`rsId`	string	Replica set identifier for the snapshot source.
`snapshotId`	string	Unique identifier for the snapshot.
`sourceMongodHostName`	string	Hostname and port of the source MongoDB instance from which the snapshot was taken (e.g., `mongodb-host:27017`).
`startTimeTs`	object	BSON timestamp object when the snapshot process started. Contains `time` (Unix timestamp in seconds) and `inc` (increment counter) fields.
`state`	string	Current state of the snapshot. Common values include `COMPLETE`, `IN_PROGRESS`, and `FAILED`.
`storageSize`	number	Total storage size of the snapshot in bytes.
`timestamp`	object	BSON timestamp object representing the oplog timestamp when the snapshot was taken. Contains `time` (Unix timestamp in seconds) and `inc` (increment counter) fields.
`totalDuration`	number	Total time taken to complete the snapshot in seconds.
`transferSpeed`	number	Average transfer speed during snapshot creation in megabytes per second.
`latestUpdateTs`	object	BSON timestamp object containing the latest update time. Contains `time` (Unix timestamp in seconds) and `inc` (increment counter) fields.
`descriptionCreatedAtTs`	object	BSON timestamp object when the snapshot description was created. Contains `time` (Unix timestamp in seconds) and `inc` (increment counter) fields.
`dataTransferStartedAtTs`	object	BSON timestamp object when data transfer began. Contains `time` (Unix timestamp in seconds) and `inc` (increment counter) fields.
`endTimeTs`	object	BSON timestamp object when the snapshot process ended. Contains `time` (Unix timestamp in seconds) and `inc` (increment counter) fields.
`error`	string	Error message if the snapshot operation failed or encountered issues.
`incrementalBackup`	boolean	Indicates whether this snapshot uses incremental backup technology.
`fileSize`	number	Total size of files in the snapshot in bytes.
`dataSize`	number	Total size of data in the snapshot in bytes.
`indexSize`	number	Total size of indexes in the snapshot in bytes.
`compressedSize`	number	Total compressed size of the snapshot in bytes.
`fileListUploadDuration`	number	Time taken to upload the file list in seconds.
`finalizeFileListDuration`	number	Time taken to finalize the file list in seconds.
`dataBlockUploadDuration`	number	Time taken to upload data blocks in seconds.
`numBlocks`	number	Total number of blocks in the snapshot (incremental backups only).
`numNewBlocks`	number	Number of new blocks in the snapshot (incremental backups only).
