 This is the main archive area to be used for large files, big datasets or archives; it is designed to be a distributed storage area for long-term data preservation. Data in this area should be stored in the form of compressed folders because the presence of a large number of small files will compromise its functionality. Every sector or project has a dedicated area with an associated quota on ''/archive/'', and when the quota is exceeded no further writing is possible on the sector or project area. This is the main archive area to be used for large files, big datasets or archives; it is designed to be a distributed storage area for long-term data preservation.
