Their backup may not be your backup.
Almost certainly not.
If your data is kept only with that one online provider ā be it email, online photo albums, online music collections, generic ācloudā storage, or more ā thereās a good chance you really have no backup at all.
The key is this: the backups online services make arenāt for your protection; theyāre for the providerās.

Cloud service backups
Cloud service providers such as email, cloud storage, and web hosts keep backups, but those backups are generally not for their customersā use. The only real backup you have access to are the backups you create yourself.
All cloud services have backups
Itās a very poor service provider that takes no backups at all. While it happens, itās usually discovered immediately prior to that service going out of business. Itās probably a common cause of that service going out of business.
Itās safe to assume major cloud service providers all have backups. They have hundreds, if not thousands, of servers, and store terabytes of data that are almost certainly backed up on a regular schedule. Their equipment breaks down just like ours, and itās extremely important they not suffer data loss when it does.
For an online provider to lose data because of a problem under their control is inexcusable. Hence, they back up, likely in many ways.
Those backups are for their needs
Hereās the catch, though: those backups are for their purposes, not yours.
Their backups are to protect them.
If their servers die, they can use their backups. If their software fails, they can use their backups. If their employees make a mistake, they can use their backups.
If you make a mistake and delete a file, get malware, or suffer hardware failure, the service providerās backups will not help.
They didnāt make those backups for you.
Two exceptions
There are two cases where your service providerās backups might serve more than the service provider itself.
First, they could choose to use their backups as part of a customer-facing restore option.
Iām not aware of any that do. 1
Second, if law enforcement comes along with a warrant or court order, it may compel the service provider to hand over their backups. This varies tremendously based on the provider, their location, and the jurisdiction of the requesting court or agency.
I suspect this happens with some regularity.
How to tell if their backups are useful to you
Test it.
I mean that literally: āpermanentlyā delete a file, an email message, a photo, or a song, and see if you can use only the cloud serviceās resources to recover it.
Unless thereās an online recycle bin or history feature, Iāll bet you canāt. Even though you know itās backed up somewhere, somehow, by the service provider.
Never assume
āIf itās in only one place, itās not backed up.ā
Your online service counts as one and only one place.
Never, ever, assume anything else.
Even if they did provide some kind of backup-and-restore feature, what happens if the provider suddenly shuts down? Itās happened, and if it does, both your online data and any online recovery service they offer would both be gone in an instant.
The only safe approach is to take control of your own backups.
- If your email is all online at one provider, use a desktop email program to back it up.
- If your photos are all online at a photo storage service, save copies before you upload.
- If your music is all stored online, download copies.
- If your data is only stored in any kind of cloud service, make certain that it is also downloaded to computers you control, and back up those computers regularly yourself.
- If you maintain a website or other online presence, back it up yourself besides whatever your web host may or may not provide.
The only backups you truly have are those you control yourself.

1: Web-hosting companies often offer some form of customer-facing backups. Those are often limited and quite separate from the hosting companiesā own backup strategies. Regardless, if the host goes away suddenly, any backups stored there go away as well.
I wouldnāt rely on only one backup method, even one system image isnāt enough.
As Leo says:
A great overall strategy for backing up is what many refer to as the ā3, 2, 1ā approach.
3 copies [eg. Original+ system image + cloud]
2 different formats [eg hard drive + cloud]
1 copy kept off-site [eg cloud, NAS, physically carry a backup drive to another location]

And thatās the bare minimum
Do your comments in the article about OSPs and backup apply to carbonite?
Carbonite is an Online Service Provider, but it is a different case. Since it an online backup, you always have a copy of the data on your computer, and being a backup system, they would have a number of generational backups for you to restore from. your
See the following article. The recovery process is different, but the principle is similar.
https://askleo.com/recover-deleted-files-onedrive/
No, because backup is their business. But my comment on testing still applies ā always good to give it a try.
Is there a difference between MS One Drive and Carbonite? I have both but we had a problem with Carbonite when we upgraded our Quick Books program ā they were unable to back up.
They both store your data in the cloud, but thatās pretty much where the comparison ends. OneDrive synchronizes everything you put in the OneDrive folder and synchronizes that with every computer and device you have signed into that Microsoft account on which you have OneDrive installed. Itās not clear exactly what Carbonite backs up but it uploads all of the folders they determine to be your personal folders, such as Documents, Music, Downloads, Pictures, Video etc.
āOneDrive synchronizesā¦..ā ā Thatās an important point. Very important. I know somebody who decided to delete data from his computer in order to free up space. He thought he could do this as his data was backed up to both the cloud and an external hard drive. Both of those backups were, however, syncs so when he deleted the data from his computer, it was deleted from the cloud and external hard drive too. The cloud service had a 30-day window in which deleted files could be restored but, sadly, he didnāt notice in time to be able to do that.
Bottom line: itās important to understand how your backup system works.
Good point. Itās important to realize that deleting a file on OneDrive, DropBox or other synchronization service deletes it from the cloud server and all synchronized devices.
Do you know of any way to backup your appointments and reminders in Google Calendar? A few months ago Google was apparently making some changes to the system, and all my reminders disappeared. Only for a couple hours, but I would feel much better if I knew I could recover that information if necessary.
I manually export them once a month or so. I donāt know of an automated solution.
I totally agree Leo. Many people mistakenly think that sending documents etc to the Cloud is all they need to do. You canāt beat a local back up to a couple of locations (Portable HDD, thumb drive or another computer).
The Cloud is part of the solution which, for many, has the additional benefit of being accessed and edited āon the runā by a PC, Laptop, Tablet or Phone.
i never use online backups, have 4 of my own, and keep all up to date!!!
FWIW, when I do a search in Gmail, messages that I ādeleted foreverā up to six years ago are suddenly back from the dead in their entirety, if they contain the search string. This may be helpfulāand scary.
Interesting from a backup perspective though.
Except according to a corollary of Murphyās Law, when you need them, they wonāt be available.
This has not been my experience. My *guess* is that youāre locating additional copies of the message that werenāt deleted. Without knowing the exact specifics itās very hard to say why, though.
Remember that any files you copy to most cloud providers are either stored by that provider on their servers un-encrypted or if encrypted by the provider before storage the provider has the key and can decrypt them. That is unless you either send files you encrypt yourself before sending or use a provider that offers end-to-end encryption. Remember HTTPS only secures files during transit to the recipient. End-to-end encryption means the files are encrypted (and decrypted) on your device with a key (password) known only to you, transmitted to the provider encrypted and stored on their servers encrypted. The provider does not know the key and so cannot decrypt the files (nor can anyone that hacks the provider). I use Megasync which uses both end-to-end encryption and versioning.
