Due to problems with Time Machine, I've switched to Backblaze as my backup. Is this as useful as Time Machine? I encountered a problem with Time Machine and it has stopped working. I tried the suggested repair path but it didn't work. I have turned off Time Machine and switched to Backblaze as my backup option. If anyone is using BackBlaze or another 3rd party backup plan I am curious how it compares to Time Machine in terms of usefulness and is there anything I should be aware of.
No, because you cannot use if for a system restore or getting files versioned earlier in time. It is often worth it to resolve the time machine issues instead.

Backblaze itself is a wonderful effective offsite backup solution, and I often recommend such a service as a fallback to timemachine.
