What Brett said, and the backups are by default inside your movies folder.
Try opening the most recent backup and see if that gets you up and running.

[Tom Sefton] “I Suppose when you put it like that it doesn’t make too much sense really. I think the rumour sites haven’t helped and overdue updates make people expect something to come. Is it September when hardware is announced usually then?”
Moore’s law has slowed to a crawl and there haven’t been significant enough GPU updates until now. I think that’s what the holdup was.

[Mark Smith] “Tape drives are robust. I have a Quantum SDLT600A drive that has been gathering dust for some years and the other day I pulled it off the shelf and loaded a tape that must be 7 years old. My experience with spinning platters as archive devices has not been so terrific….”
Well said. On older drives I haven’t had LTO backups made I have to fire them up and “take them for a walk” or it risks the motor seizing.
Trusting teeny tiny record players with your data long term isn’t a great idea. LTO is what the studios use to back up DCIs and archive editorial so that’s good enough for me.
AFAIK there are other proprietary tape backup systems, but LTO is intended to be open as to not cause future compatibility issues.
The compatibility is tied to the drive’s ability to read that version of LTO, not the software that transferred the data to it.
As of now you can still buy LTO-3 drives new.

[Craig Alan] “So each brand of LTO drive uses its own software? That would make me nervous.”
My understanding is the software that allows the tape to be mounted as an LTFS volume has to adhere to a standard so that cartridges can be read interchangeably between different manufacturers.
The different software apps are different, but the data written to the tapes and the format are not.

This reads and writes LTO 6&7 which is cool. That gives you the option to use the cheaper v6 tapes and use the 7s when the $/GB ratio starts to make sense.
My understanding is the LTFS version needs to be compatible with the OS and LTO drives you are using. I’ve worked with places who leapfrog their data to a more current version of LTO every few years.
I don’t know about using CCC with the LTO drives as I haven’t done it. I’ve used this for media managed projects I need to keep longterm, not as a running backup. For that I use a slowish RAID-1 six bay array (using CCC).

[Jeremy Garchow] “We work in a shared environment and keeping native media is much easier than trying to keep track of everyone’s import cache.
“Are you on a SAN? If so then yeah, there isn’t any advantage to have FCP X wrap QT files in most cases.
What do you mean by keeping track of everyone’s import cache?

[Craig Alan] “Are the LTO systems proprietary in any way? how sure is the future support of these systems? “
LTO-7 can write LTO-7, and read LTO-6&5 tapes. It used to be the current gen LTO could read it’s own version and one prior, now it’s the previous two versions.
Similar to MPEG, there is an LTO consortium made up of IBM, Quantum, and HP. As long as working compatible drives exist your data can be read. The intent is long term reliable data storage for major corporations, pulling the plug doesn’t seem to be on their roadmap.
[Craig Alan] “Speed compared to hard drives?”
The last time I rented some M-Tape drives it was a tad slower than a single USB 3 drive. I could play back 1080 ProRes files directly from the tape. (Pretty cool, wasn’t possible before)
[Craig Alan] “I’m kinda feeling that as SD drives come down in price and increase in capacity and reliability they will replace other forms of storage. “
SSDs have components that can fail just like spinning drives. The LTO tapes are just recordings of zeros and ones and have no electrical components to fail. For now, much safer.

[Jeremy Garchow] “I try not to rewrap anything these days, I mostly skip the import window and drag and drop straight in to the Browser.”
It has it’s advantages when passing projects off to other editors if relinking media has to happen. It takes a lot less time to relink footage from certain popular cameras.
This has greatly improved with the last pro video update though. In the other cases staying as native as possible is how I prefer to go.

LTO tapes are still the most cost effective and safest long term backup solution.
If you don’t want to invest in a system there are places that offer backup and restore services. I’m going to get an LTO-7 system once the 6TB tapes come down in price. Right now they are $135 ea.
Right now the dollars to gigabytes ratio are too close so I’ve been backing up to 2.5TB LTO-6 tapes @ $35 each.
One thing with LTO, for it to be a true backup it has to have a redundant set in case of a write error.

I sold my HVX a while back but I seem to remember if the clips aren’t flagged for pulldown removal, FCP X still removes the pulldown fields on the timeline correctly.
If you put the 29.97 clips on a 23.98p timeline, see if it looks correct if you go frame by frame. (IE no interlaced fields)
