Storage is the act of keeping your data in a secure location that you can access readily. Files in storage should be the working copies of your files that you access and change regularly.
Backup is the practice of keeping additional copies of your data in separate physical or cloud locations from your files in storage.
Storage systems often provide mirroring, in which data is written simultaneously to two drives. This is not the same thing as backup since alterations in the primary files will be mirrored in the second copy.
Backing up data can be done manually or automatically, depending on your comfort level with those systems. If doing manual backup, you’ll want to determine how often you should back up your data—you’ll need to weigh the benefits of having up-to-date backup copies against the work involved with frequent backups. Once you’ve determined how often you should back up your data, you should set a schedule for regularly doing so. Backing up your data doesn’t require backing up every bit of data every time. You can do an incremental backup, or choose to backup only the files that have been changed or added since the last backup. Incremental backups require less time and storage than a full backup.
Good storage and backup practices help protect your data and research from losses due to hardware failure, natural disaster, or file corruption. You spend a lot of time collecting your data, so ensuring you have a good system for backing up your data will prevent you from having to spend time trying to recover your files, recollect data, or redo any cleaning or analysis.
- A granting agency may require that you retain data for a given period and may ask you to explain in a data plan how you will store and back it up.
- Storing and backing up your data ensures that it will be there when you need to use it for publications, theses, or grant proposals.
- Good preservation practices help make your data available to researchers in your lab/research group, department, or discipline in the future.

|Bucky Backup||A managed service for data backup and recovery solution that utilizes IBM's Tivoli Storage. Provides high reliability, availability, and redundancy for files, applications, and servers. Bucky Backup is available to faculty, researchers, and staff. Three levels are available:|
Enterprise: Managed backup for enterprise applications and mission critical data
Lite: Affordable, managed backup that is great for backing up files, computers, applications and departmental servers
Archive: Cost-effective, long-term archival storage
|Varies, depending on the frequency of file revisions and number of versions stored. For some scenarios, the cost is approximately $1/GB/yr or lower.||Allows you to schedule automatic backups for critical data.
The archive service should not be used for backup and files you will need to overwrite. Archiving is for preserving files as they are.
|Departmental server||Your department's IT staff may offer backup.||Varies||Contact your departmental IT staff for details.|
|External hard drives and portable media -|
available at DoIT Tech Store
|External hard drives||Varies||Remember to have another backup copy available as hardware can fail. Flash drives are also available, but remember that they are easily lost and easily corrupted.|
