Lustre/HSM Google Drive copytool

ct_gdrive is an open source copytool enabling secure and transparent Google Drive cloud storage tier in Lustre using Robinhood.

  • Lustre is a parallel distributed file system, generally used for high performance computing (HPC).

  • Google Drive is a Cloud-based object storage system.

  • Robinhood policy engine is used to setup and apply policies for backup and tiering.

ct_gdrive transfers files from Lustre to Google Drive, and vice versa. Used either for Backup/Disaster Recovery or as an HSM tier to expand your Lustre filesystem, ct_gdrive directly uses the Google API Client Library for Python to minimize the number of remote cloud storage API requests needed to archive/restore files using Lustre/HSM.

Each Lustre file is stored in Google Drive using its Lustre FID as the name. When archived for the first time, a file description with some info like the original file path is added. ct_gdrive supports the upload of multiple versions of a same file to Google Drive. However, managing these versions is not supported from Lustre.

ct_gdrive should be used with lhsmtool_cmd, an open source and generic Lustre/HSM agent that launches a command when an action (archive, restore) is requested by the Lustre/HSM coordinator.

Contact info

ct_gdrive is maintained and used in production by Stanford Research Computing where we successfully pushed several millions of files and more than 1 PB to Google Drive in about a month.
