| In general accounts which appear not to have been used for more than 6 months will be locked and the data belonging to the account may be archived to tape. Access to archived data can then be obtained by contacting the system administrators. Recovering the data may take up to a few days (depending on whether the tape drive is busy with another job, how much data is to be recovered, holidays and weekends). | In general accounts which appear not to have been used for more than 6 months will be locked and the data belonging to the account may be archived to tape.

This encryption protects against the server being stolen, or being improperly disposed | + | Please see the page on [[Sensitive Data]] for a discussion of this other form of data protection. |
| - | If you have a project that includes the use of sensitive data please talk to the system administrators to see whether you should store that data on /home6, or have your entire home directory moved to /home6. | ||
