This commit adds the ability to periodically perform snapshots on
an interval that is separate from retention. For example, this lets
you retain backups for 24 hours but you can snapshot your database
every six hours to improve recovery time.
This commits adds support for non-AWS S3-compatible storage such as
MinIO, Backblaze B2, & Google Cloud Storage (GCS). Other backends
should also work but some code has been added to make URL-based
configurations work more easily.
Previously, there were excessive log messages for checkpoints and
retention. These have been removed or combined into a single log
message where appropriate.
This commit refactors the commands to allow a replica URL when
restoring a database. If the first CLI arg is a URL with a scheme,
the it is treated as a replica URL.
This commit changes `litestream replicate` to accept a database
path and a replica URL instead of using the config file. This allows
people to quickly try out the tool instead of learning the config
file syntax.
