It's very difficult to know what to expect because data transfer speed info from ISPs and Cloud services can be misleading or difficult to obtain. Add-in all of the possible variables starting with our computers, LANs (our household WiFi/Ethernet network) and WANs (ISPs, Internet, etc.) to the Cloud services. . . Well, it's a proverbial jungle out there.
Here are a few suggestions/resources that you may find helpful when researching your options. It will take some time and effort but it's worth it in the long-run. (No one enjoys switching Cloud providers after uploading terabytes of data but at least you already have an offsite backup while seeding a new one. ;-) )
Take Control of Backing Up Your Mac: The Online Appendixes The link is for online data backup services; there are other sections for backup software and hardware. Prices, features and other info are listed. Kindly note that while the appendices are regularly updated, features and prices can change at any time, so it is important to double-check things that are important to you on the service provider's website.
For example, the Backblaze prices changed last October but the old ones are still listed. The annual cost per computer is now $99 and the default version history retention period has increased from 30-days to one-year. (Unlimited version retention is available at a nominal extra cost.) I've contacted the author/publisher Joe Kissell about the discrepancy.
If you need assistance regarding what the features offer, scroll down the webpage to
Feature Explanations for This Tab.
Apparently, Carbonite does not offer versioning (retention of edited or deleted files) to Mac users. This is something that many people want even though backup software such as Time Machine has it. I like it because I do not use Time Machine or other versioning software for my local backups. Again, be sure to check with Carbonite if having it is important to you.
Other features such as
Compression, Delta Encoding and
Deduplication affect the size and speed of data backups.
Delta Encoding is most helpful after data is backed up for the first time and not just the initial seed.
Deduplication can significantly reduce the amount of storage space required and considerably speed-up backups.
According to the appendix, Backblaze uses all three but Carbonite does not offer
deduplication. Based on my limited research, Carbonite claims to provide client (user computer) and server-based deduplication.
But with Carbonite's emphasis on Windows, it may be that the former or both may not be available to Mac users. It would explain why uploads are slower. But this subject requires more looking-into. . . To be sure, Carbonite is very popular but it certainly has its detractors as well.
Which leads me to suggesting doing Startpage (Google) searches using terms such as "
Cloud-service-name here issues.) It often turns up all kind of sources and I recommend scanning the titles past the first page of hits.
Various online forums are worth perusing/searching and those (like DPR) that allow Google spiders access will show up when using Startpage/Google. In my experience Reddit is another helpful resource, keeping in mind that subReddits vary greatly in reliability LOL. You can search many subReddits without creating a free account and joining. But I ultimately joined because it's quick and painless, it's not a source of spam & I even joined some groups.
DataHoarder and other subReddits (including those sponsored by companies) can be very useful in tracking down the Cloud and other computer services providers that are worthy of receiving your hard-earned cash.
