OtoCopy

If you store a lot of your documents on an external hard disk, USB flash stick or network drive, then you need to make sure the integrity of the files is preserved, so you can access the info whenever you need it.
OtoCopy is a lightweight application that enables you to backup all data you keep on external drives continuously and synchronize the files inside along with the changes you make to them in real-time.

Easy setup and configuration

While the installation is fast and does not require any special attention from your part, you should take the time to specify the exact type of files you want to create backups for, so that the tool knows what to monitor.
The application allows you to set the parameters for the backup seamlessly and the entire process can be completed in less than one minute. More precisely, you can specify the storage folder, the directory to save, whether you would like to include the subfolders, the extensions to save and the ones to ignore, the file size as well as the minimum delay before saving, to name a few.

Enables you to synchronize the files in the folder to save

After you set up the parameters, the application recommends you perform a synchronization of the files that are located in the folder you want to backup. Depending on the size of the folder, this process can take some time. Then again, everything is done in the background, so it does not distract you from your current assignments.
It is necessary to mention that the program comes with an option that enables you to delete the files in the original directory that do not exist in the folder to copy. Moreover, it displays a report with the files that have been synced, the ones that should undergo this process, the files with errors and the ones the app ignored.

An easy to use utility to sync and backup data on external drives

All in all, OtoCopy can be a good choice in case you are storing important files on external drives and want to make sure they are accessible later on.
