I have found a few things out over the past few weeks that I figure I will share with you my faithful reader. I have had a logic controller failure on my MacBook Pro which meant that I was sans laptop for approximately 10 days. The day after I received it, less than 12 hours later, the cable modem at my house failed.
So between not having my personal laptop and then Internet access being a car ride away, I discovered some items along the way.
- Backing up Data is important, but one also needs access to the data
There are a few other tangential things I have found out as well, such as changes to my photography workflow, online instructions should not be the only instruction, unfettered Internet access can be a key item but those will be separate posts.
Using my backup solutions none of my data was in jeopardy, however using that data was the challenge. I have been using JungleDisk as my incremental off site backup solution. It works very well for me, but has some choices along with it that I was not fully aware of when I made them. Using a block copy approach I could reduce the amount of bandwidth and storage space I use, however this does not come without its tradeoffs. By making this choice I would be unable to browse the files online, I would have to actually restore them using the client software. At the time I did not think that it was a big deal as I figured I could always just install the client on another computer and get all the data back.
A key item here is that it is my off site backup. Too many people think that just having a backup is sufficient. It is not as there are other things to consider than just a hard drive or computer failure. One has to think of other ways that Data can be destroyed: “Someone stole my car! There was an earthquake! A terrible flood! Locusts!!“ Having the data off site makes it much less likely that Data will be lost.
I could have just installed the client on another computer and get all the data back that still was not going to solve all my issues. As a result of not being able to browse the contents, I am going to change my approach yet again.
Some items will be backed up using block copy, other items will be backed up using file copy, and still other items will be backed up to either Mobile Me’s iDisk or to my Dropbox account. You might wonder what data would go to what place and how to keep it all organized, well that is actually fairly easy as long as I make the right decisions when starting. Just by putting files into different locations on my computer they will be backed up in different ways. Placing items into the Documents directory will place them on JungleDisk, placing items in the Dropbox folder will be on Dropbox obviously (still waiting for selective sync before 100% happy with it), and items stored in iDisk will be on MobileMe iDisk.
The key to this approach is to make sure that a file is stored in one location and only one location for live Data. I have often encountered problems where two files have the same name, but different time stamps or on different computers, so how do I know which one is current. Since all of these items are backed up to the "cloud" of the Internet I do not have to worry greatly about the loss of data. I still do backups to DVD and secondary hard drives every so often so that I am not completely at risk. For items that I want to make sure I backup in more than one location, well I have not hit any yet, but using ChronoSync to keep a "Backup" directory in sync is my plan. This will allow me to create a directory in one of the other storage locations that is labeled KeyJDBU (Key JungleDisk Backup items), then I can use ChronoSync to decide what to copy into it and keep in sync.
This approach of also having the key items in iDisk or Dropbox will also allow for the items to be browsable without having to restore all the data. It still does not solve another key issue, do I have the access to the programs to use the data once restored? I found that quite often the answer was no. Most of this situation was my own fault as I chose what format to store the Data in. Once again I could reinstall and have the data back, but that would take a while; especially with the licensing headaches some companies have put in place (that means you Adobe). I am now considering how to handle that issue.
