Snapshots

Available since v0.8.4

Snapshots are performed on a per collection basis and consist in a tar archive file containing the necessary data to restore the collection at the time of the snapshot.

This feature can be used to archive data or easily replicate an existing deployment.

The target directory used to store generated snapshots is controlled through the configuration or using the ENV variable: QDRANT__STORAGE__SNAPSHOT_PATH=./snapshots.

storage:
  # Where to store snapshots
  snapshots_path: ./snapshots

It defaults to ./snapshots if no value is provided.

Create snapshot

To create a new snapshot for an existing collection:

POST /collections/{collection_name}/snapshots
from qdrant_client import QdrantClient

client = QdrantClient(host="localhost", port=6333)

client.create_snapshot(
    collection_name="{collection_name}"
)

This is a synchronous operation for which a tar archive file will be generated into the snapshot_path.

List snapshot

List of snapshots for a collection:

GET /collections/{collection_name}/snapshots
from qdrant_client import QdrantClient

client = QdrantClient(host="localhost", port=6333)

client.list_snapshots(
    collection_name="{collection_name}"
)

Retrieve snapshot

To download a specified snapshot from a collection as a file:

GET /collections/{collection_name}/snapshots/{snapshot_name}

Only available through the REST API for the time being.

Restore snapshot

Restoring snapshots is done through the Qdrant CLI at startup time.

The main entry point is the --snapshot argument which accepts a list of pairs <snapshot_file_path>:<target_collection_name>

For example:

./qdrant --snapshot /snapshots/test-collection-archive.snapshot:test-collection --snapshot /snapshots/test-collection-archive.snapshot:test-copy-collection 

The target collection must be absent otherwise the program will exit with an error.

If you wish instead to overwrite an existing collection, use the --force_snapshot flag with caution.

Snapshots for the whole storage

Available since v0.8.5

Sometimes it might be handy to create snapshot not just for a single collection, but for the whole storage, including collection aliases. Qdrant provides a dedicated API for that as well. It is similar to collection-level snapshots, but does not require collecton_name:

Create full storage snapshot

POST /snapshots
from qdrant_client import QdrantClient

client = QdrantClient(host="localhost", port=6333)

client.create_full_snapshot()

List full storage snapshots

GET /snapshots
from qdrant_client import QdrantClient

client = QdrantClient(host="localhost", port=6333)

client.list_full_snapshots()

Download full storage snapshot

GET /snapshots/{snapshot_name}

Restore full storage snapshot

Restoring snapshots is done through the Qdrant CLI at startup time.

For example:

./qdrant --storage-snapshot /snapshots/full-snapshot-2022-07-18-11-20-51.snapshot
