I’ve been going back and forth trying to find a good off-site backup for a long time. I do have an Apple TimeCapsule where I do backup locally, but it doesn’t backup my external drives where I have all my pictures that goes back many years and that would be a nightmare to lose. I use Arq and Amazon Glacier to backup my pictures off-site and I also use rsync to a local NAS for a local backup. But I want a way of doing backup of all my stuff, so I’ve tried both CrashPlan and Backblaze but always found them to slow for my liking. Another reason for giving up on CrashPlan was the client software that uses to much processing power and I think the client is written in Java which would explain why it’s a resource hog. Not so with Backblaze that uses only about 3% of CPU even when the settings for upload speed is set to full upload speed and it doesn’t use much memory.
There is a huge difference in upload speed between Arq backup to Amazon Glacier and Backblaze. The Amazon servers are located in Ireland so I guess much of the speed difference is that the Backblaze servers are in the US and doing backup from Sweden is slower. Hopefully Backblaze will install servers in Europe as well. For now, I’ll upload everything (current estimate 22 days) and try to use it for a while to see if it works.
