Download files¶
Scylla Manager Agent comes with a download-files subcommand that given a backup location can be used to:
List clusters, datacenters and nodes.
Search for snapshot tags.
Download files without a need for third-party tools.
Please note, that the command may require higher demand on the number of file descriptors. We recommend prefixing this command with ulimit to extend the default fd soft limit.
ulimit -n 10000
