I have a folder for each year and then go by report number. You can keep a data base in Excel cross referenced so if someone calls with an address or name you will be able to find the report. Some reprting software have data bases built in or as an add on. I have an external hard drive and save a back as soon as the report is finished. I would also suggest keeping a backup off site in case you office or home is robbed or has a fire. I have to admit I,m a little behind on that one. There are also online services where you can store data. As said before, backup, backup and backup. Don't forget to also regularly backup your inspection software if you edit your library often.
