I am currently switching over my work set up to a more mobile situation. I went from my older 2010 iMac to a new 15" macbook pro and will be purchasing a display to use for when I'm at the office. Now I can take my work with me. However, I'm still trying to solve one problem: backing up everything. I plan on using a small usb 3 ssd external drive (thunderbolt 2 ssd's are expensive!) for weekly work files and accounting backups. maybe around 256 gb max. for stuff that I need all the time. That will also help not weigh down my internal drive. But for backing up all the rest of the files? I work with large photos, and need to keep years of data stored. I have clients call who need a job done again from a few years back. I don't want to keep that all on the "small weekly drive" that I will be with me all the time. I want to store that on a larger drive for when I need it. Should I store it on a larger external drive or using a cloud storage? (example: dropbox business). I guess either way I will have enough space, but the nice thing about the cloud option is I can access them anywhere I go with internet. But what if I don't have internet for some reason when I'm out of the office? But I also don't want to have to carry around larger drive with me as well. Price wise, in the end I feel I save with the external drive, because the monthly cost of the cloud never stops. Here is the problem though, I also want to keep a time machine backup or carbon copy clone (or other similar software). I'm not sure which is best, but I notice that time machine takes up a lot of space! And it also can't be used with a cloud service. The good thing about clones is they are bootable from the external drive in case any internal failure. What do you guy think is best? To sum it up, I want to cover everything: 1. Have a small fast drive for daily and weekly work 2. Have a secure back up (time machine or clone) 3. And have all older files backed up as well and accessible everywhere. Thanks for your help.
