Be sure to back up data regularly!
Data is very important for each user, especially for the papers that we take efforts to write. However,  accidents can happen at any time.  ITSO recommends that users should back up important data in time.

Recommend: 
1) OneDrive
The University provides faculty and student with 5T OneDrive capacity, which can basically meet the data backup needs.  OneDrive can be used on multiple platforms including Windows/MacOS and Android/iOS which can be synchronized.  It is strongly recommended that you upload important files to OneDrive for backup.

2) Portable hard drive
Use additional hard drives. But be careful not to connect portable hard drive with important data to public computers to prevent computer viruses.
