You see, a salient fact here is that when I needed the original version of the file, 45 days had elapsed from when my colleague first uploaded the original version.
Either I’d modified the file before Time Machine copied it to a drive, or it may have backed up the original but deleted it later to recover space on the backup drive. The result is that it can take up to 2 hours to detect any new files, or new hard drives, or if a file has changed, or a configuration has changed.Īpple schedules Time Machine to run every hour, and Time Machine also tries to keep your Mac from being overloaded. The reason it takes 2 hours is that Backblaze runs VERY SLOWLY on purpose to try to keep the load off your CPU and disk. We designed Backblaze to be lightweight, so it might take 2 hours to reflect new numbers and find your new files.

I have Backblaze set to archive continuously, but it does take some amount of time to recognize new or changed files.
But then I worked on it right away, causing both Backblaze and Time Machine to back up only the version I had edited heavily, not the original. It synced properly in Dropbox since it was copied to my computer. So how did I manage to lose data despite these three backup systems? My colleague shared the file with me by adding it to a shared Dropbox folder. I count on it to keep a deep archive of both current files and those I’ve changed and deleted. Backblaze: A stalwart secure cloud-hosted backup provider, Backblaze has rescued several terabytes of data for me over the years.
I was glad I did when Time Machine helped recover from two disasters in the last year.
