[[list-tasks]]
=== List Tasks
--
'GET /config/server/tasks/'
--

Lists the tasks from the background work queues that the Gerrit daemon
is currently performing, or will perform in the near future.

Gerrit contains an internal scheduler, similar to cron, that it uses to
queue and dispatch both short and long term tasks.

Tasks that are completed or canceled exit the queue very quickly once
they enter this state, but it can be possible to observe tasks in these
states.

End-users may see a task only if they can also see the project the task
is associated with. Tasks operating on other projects, or that do not
have a specific project, are hidden.

The caller must be a member of a group that is granted one of the
following capabilities:

* link:access-control.html#capability_viewQueue[View Queue]
* link:access-control.html#capability_maintainServer[Maintain Server]
* link:access-control.html#capability_administrateServer[Administrate Server]

[[snapshot-index]]
=== Create Index Snapshot

These endpoints allow Gerrit admins to create index snapshots.
Created snapshots can be used as a backup of the index.

It is possible to create a snapshot of all indexes, snapshot of one index or
snapshot of one index version.

The snapshots will be stored on the server at `$SITE/index/snapshots/$ID`.
The `$ID` can be optionally provided in link:#snapshot-index-input[SnapshotIndex.Input]
or will default to the current local time in ISO8601 format.

Only snapshots of indexes that Gerrit currently writes to can be created.

Note, that the creation of multiple snapshots, e.g. of different index
versions, is not atomic. If a consistent state over multiple indexes is
required, the server has to be put into read-only mode before creating
the snapshot.

lifetime is enforced. Changing the configuration will not apply that maximum
to existing tokens. These have to be adapted using this REST API endpoint.

This migration task will run asynchronously.
