OK you have a laptop and / or a smartphone and / or a tablet and you also have data, perhaps a LOT of data. It creeps up on this hoarding of data / space. You need to be proactive to keep from losing your data. Primarily we speak of genealogy (or family / history) research and of course family photos and scans of documents, but perhaps you are a knowledge worker and use your computer equipment to produce works in your professional career too. I’ll speak of genealogical research / data and you can extend it to any other valuable data / files you may have.
Today’s blog came about from a cousin (alright second cousin, once removed), Robin. She was frustrated by losing files. So her family and friends had a nice debate over what she needs to do. Of course it is a very complex issue and needs to be customized to each person.
Let me state that designing a backup strategy that is free or low cost is almost impossible — unless you only have a small number of files (# and/or sizes) and can get by with the free: DropBox, GoogleDrive, Apple iCloud, etc.
You could conceivably cobble together a solution with enough “Cloud Services” and one account each for Robin and her husband on each service in order to build up a free usable amount of storage for backup on the Internet. OK, lets say that gets you “enough” space to do your backups. First off, you better hope the number/size of files do NOT increase — but industry studies says otherwise, that data more than doubles each and every year. You will therefore run out of “free” space. Also, you will now have to invent a bookkeeping system to keep track of which files are backed up on which service in which account. Is it getting complicated yet?
How much data do you have to backup? This is the first question you need to answer. If you have an Internet service that limits data transfers or subjects you to overcharge fees then you really need to think about using the cloud. Keep in mind that you need to backup and at some point to recover a lost file(s) — now that recovery will double those overage fees. Most people can quickly generate 30-60GB of “data” from their music, videos, books, apps, and their pictures and when you throw in their work products (which actually are the smallest part of the critical space) 30-6oGB goes quickly. My wife’s tablet is almost full and we do not use much music or video.
How do you lose files? Inadvertent deletes/drops? Hardware failures? Accidental overwrites with something else? How about malware/viruses etc. ? All of the above probably. Then you need a backup solution to cover all of those eventualities. How about if you live in Florida (Hurricanes), New Orleans (Hurricanes/Floods), Oklahoma/Nebraska/Kansas (Twisters), California (Earthquakes/Mudslides), etc. or in an area where terrorism can cause catastrophic failures (NYC, DC, Seattle’s Space Needle)?
But Stanczyk, what about my sensitive or private data (financials, non-disclosure documents, personal identity, etc.)? Where do you back that up to? Is the cloud safe? Do they lose data in the cloud? Can the cloud data be stolen/hacked? What happens when the cloud crashes and is unavailable? More worries.
By now I hope you get an idea that backup is:
- Involves Some Costs
- Requires Planning
- Custom to Each Individual / Company
- Recovery Needs to be Accounted for
- You Need Access to Backups
- Disaster Recovery (offsite)
- Need Security
You could be tempted to just rationalize that December 2012 is coming up and either the Mayan Calendar and /or the World will end and why tax your brain to do backups anyway.
Ideally, we want the following features in a solution:
- 3 or 4 copies (counting the original copy)
- 1 remote copy for disaster recovery (fire, hurricane, flood, theft/loss etc.)
- Easy / Fast recovery from the first backup (ergo 1st backup copy must be local)
- Backups allow you to recover from accidental delete (assuming delete happens after the first backup)
- If we backup data with privacy concerns then we WILL use encrypt / decrypt software before or as we make a copy
- The Cloud can be used as the remote copy
Complexity. Just keep it simple, remember the acronym KISS (Keep It Simple Stupid). Trying to do backups without spending money will add complexity. So complexity / time / money are your trade-offs. In my career, we used to say, “Good | Fast | Cheap; Pick 2″. If you want a fast and cheap backup solution it will not be any good. If you want good and fast then it will not be cheap.
Lets say you have as your work product, family trees (gedcoms), scans of documents / pictures and notes / timelines (spreadsheets) / plans – lists. This is over and above your Apps, Pics, Music, Video, etc. How much space do these files all add up to? Is it 7ooMB, 1,400MB, 2,100MB then you can probably get away with burning CDs (or DVDs). CDs hold about 702MB. Make two (or better yet three copies). You need at least three copies (original plus 2 more).
Put one CD in your bank safety deposit box (if it fits). Send a second CD to one of your family members (preferably another genealogist who lives at least 90 miles away from you). The remote CDs provide for a disaster recovery in case of something catastrophic happens at your residence. You can always retrieve the CD from the bank or your family member who may be outside the area affected by the disaster. Obviously, the further away your other copies are, the longer it will be before you can gain access to them to begin recovery — but the securer the disaster copy will be. This is fairly cheap. The flaw is … you keep getting more data / files or the files keep growing. Your family tree changes repeatedly (additions and subtractions). Sometimes you can rewrite the CD (if there is still space) and sometimes you cannot rewrite because the CD does not allow for rewriting or the space is insufficient to handle the larger file. Also if you have 30 GB that needs to be backed up or more then CDs are not viable because you need too many CDs. It is also hard to keep track of multiple versions in case you need to recover from a version that is not the last backup version. I do not recommend CDs but it is fairly simple and fairly cheap.
You can also substitute DVDs, USB drives (also called thumb drives) for CDs which provide greater space.
