Meanwhile, CBackup offers 3 different types of file versioning for free. You can select any one of them according to your backup need. When you set up a backup with CBackup, it provides you 3 backup versioning options for free: Keep all versions, Keep only X Recent versions, Keep the version within the last X days.

Clean Version3

Keep all versions: CBackup will backup and keep all unlimited versions of your files.

Keep only X Recent versions: CBackup will keep the last X versions. When the backup version is more than X, CBackup will delete the oldest version automatically.

Keep the version within the last X days: CBackup will backup the latest X-day version. When the backup version exceeds X days, CBackup will delete the versions.

In addition, CBackup is very safe for your data. CBackup’s authorization system is based on OAuth, which is a standard authorization framework that enables third-party applications to connect to cloud services without a username and password. During your backup, CBackup will never read your files. All your data will be saved on the cloud you trust.


Backblaze is a backup software that most users can afford. It also offers unlimited versioning, though not free features.

Backblaze provides all cloud backup with versioning for 30 days. If you want 1-year version history, there is an additional charge of $2/month. Permanent versions are similar to 1 year, with an additional charge of $2/month for file versions modified 1 year ago, plus $0.005/GB/month.


Backblaze doesn't limit upload speed or lack security features, it provides AES 128-bit encryption at rest and SSL encryption during transmission. But for people with multiple computers, it's not an ideal backup software option. This is because Backblaze accounts are limited to one computer. If you need to use it on multiple devices, the cost will increase significantly.


Memopal is an online backup service supporting Windows, Mac, Linux, Android, iOS, and Blackberry operating systems. It can save all the versions of your files. You can search for any file name, and then its history version will appear and be restored.


All the versions of files will take up the storage space. Once you sign for a new account, you will be given 3GB of free plan. If you need more backup space, you have to pay for the Memopal annual plans (Pro, Business, or White label), which are capped at 5TB.


Carbonite is an online backup software for Windows supporting unlimited versioning. There are 3 different unlimited backup options for users - Basic, Plus, Prime. The Basic plan costs $71.99/year and the Plus plan needs $111.99/year, the Prime plan requires $149.99/year.


Carbonite provides 128-bit/256-bit AES encryption at rest, private encryption, two-factor authentication. However, the transfer speed is not satisfying.


SOS online backup is an integrated local and online backup tool that provides unlimited versioning. SOS allows you to backup, restore, and access previous drafts of files. The 50GB of storage space plan is charged for $4.99 per month, allowing you to backup from 5 PCs and unlimited mobile devices.


SOS also has top-notch security and lots of advanced services. However, looking through the SOS interface is a challenge. It is not easy to see and find your target.


CrashPlan is an easy-to-use software with end-to-end encryption. It supports keeping file versions at 15-minute increments. The advantage of CrashPlan is that it allows you to choose a certain date and time and all the files backed up at that moment will be accessed.


CrashPlan also has high security, providing AES 256-bit encryption at rest, AES 128-bit encryption in-transit, private encryption key, and two-factor authentication. But compared with other online backup software, the uploading speed of CrashPlan is slow actually.


ElephantDrive is an online backup software that performs well in NAS backups. It also provides an unlimited versioning feature. Once you back up with ElephantDrive, you will be given unlimited access to its previous versions.


ElephantDrive is mainly designed for business users. So it is not the most user-friendly software and not so easy to use and set up.
