There have been a couple. The deal is that lastlog is a
sparse file that is
indexed by UID. On an x86_64 system, UIDs are 32-bit, which
means a 1.2TB
file, but because it's sparse, it doesn't actually take up
any disk space.
It does make a good test case for whether your backup method handles sparse files gracefully, though. And how long it takes to read through even if it does.
Legato Networker packs a sad (it handles sparse files, but it takes a *very* long time to do so). ;-)
