Files from Non-Users¶

Receiving a file from a collaborator who is not a NERSC user can occasionally present a challenge, though new tools have arisen to address this issue in recent years. Following are some approaches that may be helpful in coordinating a data transfer, based on how large the files are.

For smallish files (<100s of GBs), your collaborator can¶

• Send as an email attachment
• Transfer via a common server for which they and you have logins using scp, sftp, or rsync
• Share via a cloud storage provider that you both use, such as Box, DropBox, Google Drive, Apple iCloud, or Microsoft OneDrive
• Share via file transfer service such as WeTransfer or DropSend
• Post world-readable on a web server somewhere and send you the URL
• Send you a physical USB thumb drive or CD/DVD
• Sign up for a NERSC account and get added to your project
• Use a file sharing service at their or your home institution

For largish files (100s of GBs or more), your collaborator can¶

• Transfer via a common server for which they and you have logins, using bbcp or gridftp
• Share via a cloud storage provider that you both use such as Amazon S3 bucket, Google Cloud Platform, or Microsoft Azure Blob
• Share via paid-plan file transfer service such as WeTransfer, FileMail, or MyAirBridge
• Post in a world-readable Globus collection and send you the collection identifier
• Sign up for a NERSC account and get added to your project
• Use a file sharing service at their or your home institution
