We have limited space for keeping old backups, but we now (as of June 2019) keep the last 4 mirror copies of the data. If you accidentally delete a file and wait more than a month to ask a system administrator to recover it, they won't have it. But in the case of a real disaster happening to the cluster itself, we will have a pretty recent copy of the data. | We have limited space for keeping old backups, but we now (as of June 2019) keep the last 4 mirror copies of the data.

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.
