I support a couple of companies that run EMC2 on commercial machines and they run 2+ shifts per day. If I were you I would pull that hard drive and clone it to an image ASAP and then setup another computer. Do it on the weekend if you have to after you catch up on some sleep. If you think you are working hard now just wait until that hard drive takes a dump at 10pm. I don't know if you have a Sata or IDE drive in that PC. But if you get a Drive to USB adapter (About $20 from Newegg and others), you can pop that drive out, make an image onto another computer for safe keeping and replace the drive in about 30 minutes. Then use the image to burn another copy of the drive and setup another PC. R-Drive running under Windows works fine for backing up and cloning Linux drives. (Yes, I am aware that I am a confused Windows/Linux user.. ;-) ) Acronis does not work for EXT linux partitions, at least not with the version I have. I'd be one nervous guy if I didn't have drive images of all of my customers PCs. Every hard drive will fail. It is just a matter of when. The later EMC2 software is well worth the upgrade effort. There have been hundreds of tweaks and fixes that make it much more robust.
