backing up 2T worth of footage–overworking drives?
hello,
apologies for what may be a stupid question, but i’m a bit paranoid of losing footage—
i’m planning on backing up my entire project drive (about 3T’s worth of footage) onto another drive, using media manager.
i know it’s going to take a long time…just backing up my 1 hour sequence took 5 hours.
are there any dangers i should be concerned about with working the drives for such an extended period of time?
thanks for any advice/suggestions.

Not that I know of. Just backed up 12TB of material last week and it took about 22 hours to move it all onto the backup drives. I’m using all 2TB Drives in WiebeTech RTX units.
I don’t bother with Media Manager. I just drag over the Capture Scratch and all related folders manually. I never bother with the Render files though, I’d rather just re-render in the future if I need to.

I do it all the time, backing up a 2TB G-DRIVE to another one using Mac Time Machine. Never had problems with it.

thanks walter….
so you drag/drop?
is there any particular reason you do this, instead of copying via media manager? i was under the assumption that the later was safer.
thanks.

Media Manager will not make transfers “safer”, as the actual copying is still being executed by the Finder. It integrates to your FileMaker environment and permits advanced logging and managing of media locations and properties, which can be worth a lot depending on your database procedures, but there is no true added safety compared to dragging and dropping.
One thing to keep in mind when backing up by drag/drop is Mac OS’ behaviour around merging and copying. If you have folders using the same name on your source and destination, when you copy over, the source will crush the destination and all its contents. I’ve heard of people losing loads of valuable data this way. It’s a very basic mistake that is way too easy to make, especially if your file- and folder-naming procedures are not airtight. Merging folders is safer, though it can be tricky. A primer on merging can be found here: https://macmost.com/merging-folders.html
Personally, I prefer doing this through Terminal, but people call me a geek so I may not be a reference there.
Modern HDD’s can take the prolonged transfers without problems. Most drives will switch off before any temperature issue becomes fatal in the worst of cases. Some drives will break over time, inevitably, but that’s why we back up in the first place.
