# Housekeeping
> [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/3041) in GitLab 8.4.
## Automatic housekeeping
GitLab automatically runs `git gc` and `git repack` on repositories
after Git pushes. You can change how often this happens or turn it off in
**Admin Area > Settings > Repository** (`/admin/application_settings/repository`).
## Manual housekeeping
The housekeeping function runs `repack` or `gc` depending on the
**Housekeeping** settings configured in **Admin Area > Settings > Repository**.
For example in the following scenario a `git repack -d` will be executed:
- Project: pushes since GC counter (`pushes_since_gc`) = `10`
- Git GC period = `200`
- Full repack period = `50`
When the `pushes_since_gc` value is 50 a `repack -A -d --pack-kept-objects` will run, similarly when
the `pushes_since_gc` value is 200 a `git gc` will be run.
- `git gc` ([man page](https://mirrors.edge.kernel.org/pub/software/scm/git/docs/git-gc.html)) runs a number of housekeeping tasks,
such as compressing file revisions (to reduce disk space and increase performance)
and removing unreachable objects which may have been created from prior invocations of
`git add`.
- `git repack` ([man page](https://mirrors.edge.kernel.org/pub/software/scm/git/docs/git-repack.html)) re-organize existing packs into a single, more efficient pack.
Housekeeping will also [remove unreferenced LFS files](../raketasks/cleanup.md#remove-unreferenced-lfs-files)
from your project on the same schedule as the `git gc` operation, freeing up storage space for your project.
You can find this option under your project's **Settings > General > Advanced**.
## How housekeeping handles pool repositories
Housekeeping for pool repositories is handled differently from standard repositories.
It is ultimately performed by the Gitaly RPC `FetchIntoObjectPool`.
This is the current call stack by which it is invoked:
1. `Repositories::HousekeepingService#execute_gitlab_shell_gc`
1. `Projects::GitGarbageCollectWorker#perform`
1. `Projects::GitDeduplicationService#fetch_from_source`
1. `ObjectPool#fetch`
1. `ObjectPoolService#fetch`
1. `Gitaly::FetchIntoObjectPoolRequest`
To manually invoke it from a Rails console, if needed, you can call `project.pool_repository.object_pool.fetch`.
This is a potentially long-running task, though Gitaly will timeout in about 8 hours.
