Currently, both tape libraries are located in the same robot at the SEGI. However, The 2 tape librairies are situated at the SEGI and in the CHU data centre, so the 2 copies of each file/folder are in 2 different locations.
in February 2021, we'll add a new robot at the CHU datacenter, and one of the tape
library will be moved there, so that the 2 copies will be in different locations.

The 2 tape libraries used for the backup of files and for the offline archiving system are currently almost full. With the help of the SEGI, we have already taken action months ago to increase the storage capacity and things are moving forward, but the procedure is quite long and it won't be possible to send any file to the offline archiving system before the extensions are up and running (probably in October or November 2022).
