You Say Bytes, I Say Bits, Let's Call The Whole Thing Off

 I need help calculating upload speed times.

Our home connection uploads at 5 Mbs (bits).  In the fall a friend will have access to a 1 Gbs (bits) upload speed.

If I have around 1 TB(ytes) worth of data to upload, the math looks like this

1. Upload from MD's home = approximately 20 days (rounded up)
2. Upload from friend's location = 2-2 hrs

Now here's where it gets tricky. Some online backup servers cap the data flowing into their servers. Ex Sync.com caps it at
5 MB(ytes) or 40 M(bits)

In which case my math looks like this

1. Upload from MD's home = approximately 20 days (rounded up)
2. Upload from friend's location = 55-60 hrs (2+ days)

Did I get this correct?

I used this calculator

I would consider a service that accepts external disks....

You need to add an additional amount for not getting exactly 100% of your expected throughput. I would also find out how good the resume upload works as otherwise you will never get a good upload.

Numbers look fine to me via wolfram alpha :

18 days.

55 hours

Thank you so much!! I was worreid I had messed up with bits vs bytes. My home bits upload is supposed to be 5 but I usually get 2-3. So my plan was to double the time estimates. And frankly, there is no way we'd use the home upload. We'll need to find someone with fiber if we cannot find data storage that seeds.

And speaking of that....We're running onto a problem finding someone who seeds or accepts a hard drive for the initial upload.

Here is a partial list of what we need. The project is (a) backup and (b) online crowd-sourcing of a catalog of files. The access requirements for the catalog portion of the project means we're looking for more than just cold storage.

Need initial "seeding" for 2-3 TB (if the provider does not offer a USB shuttle seed service, determine if (1) provider limits upload speeds and (2) the team will need access to a fiber/T1 upload node)

Assume a max 5 TB month download bandwidth during the crowd sourcing project

Need to limit access to the files - ex logged in collaborators only or password protection. All users need DL access, some users will need upload access

Files must be able to be downloaded in zip files or by folders - not just one single file at a time. FTP is a bonus but not every volunteer will use it, so it should not be the sole option for data transfer.

Authorized users who access the files do not need to give credit card or go through elaborate authentication process (ex AWS or Google Services are not end user friendly)


So far we've looked at
AWS
Google Cloud services
IDrive
Sync.com
Box.com (Business)
Dropbox (Business)
BackBlaze (the shuttle/seed cost is too high)


Best upload speeds and resume is coming from Box.com (which also supports FTP). Also allows preview of some of the video files.

Hey, I don't know about your math but I have 150 MB/s upload speed which is faster so if you want to send me the thing and have me set it uploading I'm happy to do so. :)
