It appears as though I need to reformat my computer which is my personal computer. I would like an online backup for some assistance in this. Can anyone here who has backup services send me a quote for 7 days of service

How much data you talk about ? and isn't it much easier to just get yourself a USB external harddrive and push the data to there ?

Well I'm looking for around 50 gigs.

I think any non-oversold host would be able to facilitate you with your request; as they are not oversold it should be possible without any issue to use the space for a backup (but check their TOS, some may have restrictions in the typo of files)

You are aware that most connections have a bad upstream and it can take quite long for you to upload 50GB?

Simply get a external hdd or borrow a Laptop from your friend. Uploading/Downloading 50GB data is painfully slow
