How to control data tape movement during COVID19

For ISO certified organizations, this situation can be addressed through a management review (during the normal scheduled meeting, or by means of an extraordinary meeting), where the situation is presented to Top management, and they can decide for the proper course of action (e.g., accept the risk of not keeping backup tapes on off-site location during the isolation period, apply another type of control, or change the current procedure/technology to overcome this physical movement of backup tapes).

Clause x - Backup
Clause x.x - Backup procedure during a pandemic
In case of a pandemic, the backup procedure must be made as follows: <from this point you must include the procedure specific for this case>
