The file system of each node is shared via [NFS](https://wiki.archlinux.org/title/NFS) with all other nodes over the fastest Ethernet link available (i.e. 10 Gbit if both nodes are connected to the 10 Gbit switch, or 1 Gbit over public network otherwise).
For example, user data from `gp1.fjfi.cvut.cz` is available on other nodes in `/mnt/gp1/`, and so on.
Note that only data on the large disk arrays on `gp2.fjfi.cvut.cz` and `gp3.fjfi.cvut.cz` have the same location regardless if they are accessed locally or over the network (on other nodes the local path starts with `/home/` rather than `/mnt/<nodename>/`).

> __Warning:__ There is __no backup__ for file systems that store user data.
> Even disk arrays on `gp2` and `gp3` are not backed up, since they are on RAID 0 and even __a single drive failure would mean destruction of all data__.
