File versioning refers to every edited version of files, and all versions will exist simultaneously. Meanwhile, you can restore the problematic files to any previous kept version, including, corrupted or damaged files, accidentally deleted files, overwritten files.
Actually, whether for local or online backup, the more backup versions you have, the less likely your data will lose. But some cloud backup software will limit the number of backup versions or retention time, for example, Acronis keep the backup files up to 3 years old and 99 copies.
For every cloud backup user, backup versioning is very important. But looking at only one aspect, it’s difficult to find out which service provider is the best. Therefore, we’ll consider various factors in this article.
Except for backup versions, security, price, capacity, speed, external hard drive or mobile backup etc can also be a factor. You can also list your preference and then see below.
Crashplan allows users to retain file versions at 15-minute increments indefinitely, which is the closest to unlimited backup versioning. And you can keep the deleted files forever. In addition, you can access all files backed up at that moment by data and time rather than a single file.
Crashplan charge $10/month for unlimited cloud backup and external hard drive backup. The price is charged monthly, so you can stop at any time.
Also, it has a strong security, including AES 256-bit encryption at rest, AES 128-bit encryption in-transit, private encryption key, two-factor authentication.
Honestly, compared with Acronis True Image and Backblaze, the uploading speed of Crashplan is relative slow.
Meanwhile, it supports multiple useful features, such as, external hard drive backup, mobile backup, automatic cloud backup, throttling, block-level copying etc.
In a summary, Crashplan is our first pick. All things are fine, the biggest disadvantage is its lower uploading speed.
Backblaze’s all cloud backup plans come along with 30 days versioning backup. In addition, to my surprise, from October 8, 2019, the version history has been extended to 1 year, or even forever. The 1-year version history asks additional fees of $2/month and the forever version is similar to one year, at an additional $2/month plus $0.005/GB/month for file versions modified more than 1 year ago.
For unlimited backup, you need to pay for $5/month per computer. Also, you can get a $10 or $25 discount by paying for a year or two in advance.
And there is no lack of security features, it supplies AES 128-bit encryption at rest, SSL encryption in-transit, private encryption key, two factor authentication for unauthorized access.
The transfer speed become faster, because Backblaze does not limit the upload speed. The only factor that slow down transfer speed is the distance to the servers in California.
In addition, it has many excellent features, such as, automatic backup, mobile backup, offline restore, mail restore, drive shipping, and more.
In sum, Backblaze will be a great option if you only need to backup one computer. But if you have multiple computer, the cost will increase significantly.
Acronis offers user an option to set retention time and the number of backup versions, but it still has restriction. The retention time is up to 3 years old and the maximum number of retained versions is 99. And the premise is that you enable the delete option. If not, Acronis will always keep your files.
Acronis charges $21.66/month for 5TB space. Compared with other cloud backup service, the price is very expensive. And it does not have unlimited plan.
Also, there is no worries about security, it provides AES 256-bit encryption, TLS/SSL protocol in-transit, Acronis active protection, zero-knowledge encryption as well as key cards, biometric scanning, patrols and monitoring. Unfortunately, it does not support two factor authentication.
At the same time, its speed is fast, for example, a 1GB folder only takes 15 minutes.
In addition, it still supports other useful features, such as, external hard drive backup, mobile backup, social media backup, file sync and file sharing, and more.
Like other cloud backup service, Carbonite also supports versioning backup. It keeps three versions of files and all versions will be retained for up to three months, the first version for seven days, the second version for three weeks and the third version for two months. And the deleted files will be reserved for 30 days. Please note that Carbonite backup versioning is only for Windows.
Carbonite's unlimited backup is more flexible, because it offers users three available choices, including Basic, Plus, Prime, and you could use the most proper one.
The basic unlimited plan costs $71.99, the Plus charges for $111.99 and come along with external drive backup and automatic video backup, the Prime ask price $149.99 and come with courier recovery service. All plans are charged annually and you can get 5% or 10% discount separately if you pay for 2 or 3 years ahead of time. In addition, you have 15 day free-trial for test.
Security is also a key feature in Carbonite. It provides 128-bit /256-bit AES encryption at-rest, private encryption, two-factor authentication.
By comparison, the transfer speed is inferior, and on the initial backup, you will spend much time uploading the same amount of files. But the block-level algorithm will greatly improve the speed after the initial transfer.
At last, Carbonite also has its own useful features, such as, automatic photo backup, backup by file type, external drive backup, mobile backup, schedule backup for up to 5 computers, etc.
Versioning backup is almost for every cloud backup providers, CBackup is not an exception. It supports unlimited backup versions forever and you can choose to delete the useless cloud backup file versioning.
The unlimited backup will not cost you a cent. All you need to do is add multiple cloud disks to get enough space.
The data and account security are ensured by OAuth, so please feel free to backup files to cloud, transfer files from Dropbox to Google Drive, and so on.
The transfer speed between cloud disk mainly depend on cloud disk limitation, that’s to say, how many files are transferred on the disk per minute. What’s more, the limitation is different on different clouds.
In addition, you can also enjoy other useful features in CBackup, PC to cloud backup, automatic cloud backup, filter settings, email notification, allocate space, combine cloud storage, and more.
Speaking of cloud backup with file versioning, you may need a service that can provide unlimited backup versions. It can be a key feature when you consider cloud service provider, but not the only factor. You can list your other preferences and see if the software recommended in the article has these features, then choose the most proper one for you.
