Velocity End of Life addendum: Replacement Suggestions
May 2nd, 2019
Earlier this year we sent out an email letting everyone know that the Velocity file transfer service will be completing its service life on May 24th, 2019. We are just a few weeks away from turning off the service. Please remember to have any files that are stored on Velocity moved to another storage service before the 24th.
Here are suggestions for replacement services for file transfers.
- Google Services with Google Drive: Most users will have success using NC State University’s Google Storage services. The amount you can store and transfer is unlimited. You will have access to a single drive. You can attach files in your NCSU email directly from Drive. You can also have Team Drives created for specific teams. Access and security are excellent for all but ultra sensitive (purple) data. Please go to the NC State University Drive – G Suite site for more information.
- Microsoft 365 OneDrive: A few folks have contacted us about issues using Gmail and Google Drive with outside organizations. If you have problems with Google Drive, an alternative is OneDrive. Everyone on campus has access to Microsoft 365 and that allows you use of OneDrive with 1TB. To share documents and files with others, Microsoft has a step-by-step process to show you how.
If your need for sensitive data transfer is ultra-sensitive(purple), there are solutions available to you. However, you will want to work with your assigned data steward for the best solution for your data storage needs.
Please note: If you are storing anything on Velocity, please transfer your files to your Google drive or a secure file system that your department has approved for safe storage. Velocity was only designed as a file transfer service.
Also, know that Velocity is a minimally secure file transfer service. Google Drive and Microsoft OneDrive have been approved for highly sensitive(red), data and are more secure than Velocity.
Velocity End of Life (Original article, January 29th, 2018)
A Brief History of the Service
After many years of use, the Velocity service (velocity.ncsu.edu) is being shut down. We’d like to take the opportunity to share some history of the service, and explain the reasons for why the service is being retired.
Velocity was created in 2008 by Alan Gerber in the College of Natural Resources in response to faculty needing to physically mail disks in order to transfer data between institutions. When Alan moved to the College of Humanities and Social Sciences a few years later, the project followed him, and CHASS supported and maintained the service. In October of 2015, CHASS decided to sunset the project; however, since the College of Engineering made frequent use of the service, ITECS adopted the project, moved it onto new hardware, and modified the code to work with the new Shibboleth authentication system.
Current Usage Data
Although the original intent of the Velocity service was to provide a digital transfer service for large files, the usage of the service today has veered more towards generic online file storage. At the time of writing, the 11,963 files currently stored in velocity have an average lifespan of 3.43 years (with a median value of 3.69 years).
The service is also not currently used mainly for “large” files. The average size of a file currently stored in Velocity is just under 200MB (and the median value is just over 2MB). With the current state of storage and bandwidth, we’re rapidly approaching the point where a gigabyte of data is no longer considered exceptionally large. In fact, of the 11,963 active files, only 418 are larger than 1GB, with the largest being 250GB in size.
The State of Online Storage
Since the project’s conception in 2008, the availability of reliable online storage has blossomed to provide a wide array of solutions. Google, Amazon, and Microsoft offer cheap, reliable online storage services for long term file storage. In particular, with the agreements that NC State University has with Google, each NC State user has unlimited free storage via Google Drive.
Velocity End of Life
Due to the current usage patterns of the service, and the broad availability of online file storage solutions today, we have made the decision to retire the Velocity service. Velocity will continue to operate “as-is” until May 24th, 2019, and users are free to continue to use the service as a file transfer system until it is shut down at the end of May. Please note that with the retirement of the Netbackup service in October, there are no backups of the data stored in Velocity, and we will be unable to recover deleted files.
For most users of the service, Google Drive should act as an acceptable replacement for transferring and storing files. We recommend using Google File Stream for files over 500MB in size rather than the web interface.
