VERY LARGE backup to 7Zip - I am crazy?

Am I crazy for trying to run a 2.5TB backup to a 7zip file, to a 100mbps nas? Also, a nas that never runs anywhere near that...

Okay actually I just bought a new USB 3.0 enclosure, which should be here by wednesday lol.

But still... even to a USB3 enclosure... am I crazy for thinking that my little ole' laptop will be able to handle a 2.5TB backup to a 7zip file? I've been running to my local drive as a test for almost 20 hours now and its white-ing out at only 35GB.

For these types of very very large backups, should I just be using the sync/mirror?

And if so, what if I split up my backup into 2 jobs... 1 job for audio/video folders, with no compression, just on sync, and then 1 job for all other files to a 7Zip target?

Would I be overcomplicating things too much, or would I be saving a bunch of hassle and time?

I've never done more than just a simple mirror/sync to my crappy old nas, and only this year am I saving tons more video (live shows, youtube videos, gaming videos, etc etc), and I have to say... I feel like a total n00b.

Thanks for any advice you guys have for me!

I

am not sure either on their own is a sensible move, video won't compress very well so Backup won't give very good results. I am not aware of anybody who has used Toucan for such a large backup in any case, I would suggest trying 7Zip directly if you still wish to do a backup.

Sync is probably not ideal either, a quick check with Wolfram Alpha shows that simply copying 2.5TB of data at 100mpbs would take two and a half days Toucan just isn't optimised for such large copies over a network, I certainly couldn't guarantee it would work especially well.

Your split suggestion would probably work best, it saves you wasting time compressing the already compressed files and compressing the rest to reduce the cost of copying over the network.

Thanks for the advice. I have

Thanks for the advice. I have my enclosure now, so the nas is going to be donated to a family member soon. I had to go with a USB2+eSATA enclosure rather than USB3, but already the sync is flying by on USB2 compared to that old nas, with an eSata controller on the way.

Also, that estimation of the nas was actually very generous. The sync I just did took over NINE DAYS STRAIGHT... and I ended up cancelling it before it even got done testing. Stupid fbackup wants you to do the pro version in order to resume a failed backup, which is why I ditched them for toucan.

After your input I'm definitely going to write several backup jobs that sync compressed file folders (videos, jpgs, mp3s, etc) but 7Zip documents and apps, and link them together with a dos batch file.

BTW you are aware that the latest test beta seems to hang a lot, and either doesn't work or is confusing on preg rules, and the current latest official release crashes on rules... yes?

(I downgraded to 3.0.3 anyway though, so its all good)

I am

aware of the issue with 3.0.4, but if you could give some steps to reproduce any problems you have with 3.1 Pre-Release 12 in it's thread that would be very helpful.
