We are 2 months into the new year. This would be a good time to backup your shop information for this year to prevent loss. Spreadsheets can be renamed so that you get a safer copy if you can only backup to the same computer, though at the present my files are on a thumb drive and being copied to different computer entirely. Come June I will do a 6 mo backup to an external drive, but for now having the info on 2 computers and a thumb drive should offer plenty of safety net.
