Backups suck (but we need them)
Backups are hard to do, boring, thankless tasks, and often one of the things that gets pushed to the back of the pile. And yet protecting data is probably the most important responsibility for most SysAdmins.
The computer systems we install, maintain, and our users rely upon daily continue to store more and more data. Disasters and accidents will happen, and will lead to you losing some or all of that important data.
