Back Up Methods Sony EX-1

[Roger Hendrick]

We also back up to LTO tape. We have LTO-4 drives at work. Projects are moved to a mirrored NAS for near term storage then archived to LTO tape from there, on a schedule. For P2 and XDCAM-EX footage we offload cards directly to both the NAS and local RAID. We used to use BD-R to archive but we prefer this NAS to tape arrangement – much faster/cheaper and we have lots of redundancy both locally at the workstation and within the NAS. The tapes are bullet proof, *excellent* error correction, large capacity and fast (though we usually run backups overnight).

As far as price, yes new LTO-4 *is* expensive, however I just picked up two LTO-2 drives off ebay for about $80 each. I’ll use one in my home studio hanging off an old G4, running Ubuntu as a simple RAID 1 NAS / backup station. Now I’ll have the same industrial quality backup for my home network. The other one is kept as a spare (a no-brainer given the price).

LTO-2 is good for 200-400GB per $30 tape and the LTO spec (which is open source unlike DAT or DLT) specifies that you can read back from at least two generations of future drives. The tape data *mounts* so copying from LTO-2 to any newer LTO flavor in the future will be easy (our to some other BU option – the *cloud* maybe??).

Only recently discovered that the EX clip browser will “split” folders into 4.7 gig chunks so you can go to regular DVD’s. Handy if you don’t have a lot of footage. Other than that, get ready to pay the ferry man!

Thanks everyone for the information on back up workflows. Great insight.

that’s strange. Ive heard about blu ray and tape drives but what about straight forward internal disk hard drives?
i use two 1.5 terrabyte internal sata drives to store and access footage. i keep my BPAV files on the one drive and the mxf files on the other. If you work natively with BPAV files then you can keep BPAV files on both drives.

I worked it out that even by having to use two drives, one for backup and the other for working on, i only costs slightly more than if i were using MINI DV tapes.

Most computer motherboards these days come with more than 2 sata hard drive linking cables, So you could have your footage drive hooked up and your back up drive hooked up, and then also your operating system on a seperate drive. Depending on the amount of avaliable connections you could also have a seperate drive for jus your render files.

So in short i say backup on: internal hard disk drives
