Load Database

The load command restores a database from a backup. It can restore a single database or all databases from the latest backup taken.

The command supports restoring from local files, as well as from S3 and Google Cloud Storage buckets.

Usage

./load [GLOBAL_OPTIONS] [OPTIONS] [DATABASE...] DESTINATION

Global Options

These options are passed to the mongorestore command.

  • -h, --host: The hostname of the MongoDB server.
  • -P, --port: The port of the MongoDB server.
  • -u, --username: The username to authenticate with.
  • -p, --password: The password to authenticate with.
  • --authenticationDatabase: The database to authenticate against.
  • --ssl: Use SSL to connect to the MongoDB server.

Options

  • --compression: The compression used for the backup. Can be gzip, lz4, bz2, or none. If not specified, the script will try to auto-detect the compression from the file extension.
