git maintenance command [options]

git maintenance manages repository maintenance tasks automatically. It handles garbage collection, commit graph updates, prefetch, and incremental repack either on-demand or through scheduled background jobs.
Background maintenance improves repository performance over time without manual intervention. The `start` subcommand registers the repository and sets up a system scheduler to run tasks periodically. Configuration controls which tasks run and how frequently.

start

Enable background maintenance.

Disable background maintenance.

Run maintenance tasks.

~/.gitconfig

Global maintenance configuration for scheduled tasks.

$ [maintenance]
    auto = true
    strategy = incremental

Background jobs need system scheduler. Some tasks may be slow. Configuration in git config.

git maintenance was added in Git 2.29 to provide automated repository optimization, replacing manual gc invocation.
