A bit silly. I tried setting up rsnapshot to make snapshots of the entire filesystem on my server. This apparently led to a fatal exception in the Linux kernel, probably when rsyncing /dev and especially /proc. It took a bit of time before it was fixed, but everything is working fine again. I'll make sure to first try silly things such as backup / localhost on my laptop.
