Downloading a Backup File

  1. Specify an empty download directory; if there is no directory, create one by running the following command:
mkdir dump
  1. Run the download command with the download link obtained from the TencentDB for MongoDB Console. For example, if the download link is cmongo_backup/cmgo-pfsumk5l_0/snapshot/1544517026 , the command will be as shown below:
coscmd  download -r  cmongo_backup/cmgo-pfsumk5l_0/snapshot/1544517026  dump/
  • A replica set has only one download link.
  • Each shard of a sharding cluster has a download link. Different shards need to be stored in different directories so as to prevent the downloaded data from being overwritten.
  • The -r Must be added to the command for downloading folders.
    1. After the download is completed.
