In my line of work as an IT consultant I frequently recommend Arq to my clients.What I like about the application is that it is so secure in that it uses advanced encryption standards and that the data only leaves the computer after being encrypted with a password known to the owner. Some other outstanding features are; 1.Backups are stored in your cloud account, NAS or SFTP server protecting your data against theft, ransomware and disaster. 2. Periodic automatic backup. 3. Can be integrated with other cloud storage service providers. 4.Unlimited backup. 5. The app also keeps multiple versions of your files so that if you discover a file is corrupted, go back in time to get an earlier version. 6. Open and transpararent

Arq Backup does a good job with hourly backups to the cloud inexpensively. I also am glad for their strong encryption processes, which is one less headache I have to worry about.

The best thing i like about Arq is that it do not limit you to file sizes, that's why i can store encrypted files on cloud without fear. second best thing is its Versioning of files it do automatically, So if your new file is not working you can easily get last version of file. third good thing is it is very inexpensive, so to use it i don't have to think about cost.
