All 4s.io users can enjoy the “backup files” feature. Our Premium users can back up even those files which are deleted from the ‘Trash’ folders in accounts. Backup online services are very important nowadays.

4s.io provides you with assurance that your files will be safe. Your photos, documents, music, etc will stay unharmed.

Reasons that may damage data:

• unexpected Internet disconnections;
• electricity problems;
• broken computer;
• accidently erased info.

All these factors can’t damage your files when they are protected by 4s.io.

One more solution for simple backup of files online is 4s.io Sync. After installation of this brilliant app you just work with your “My 4s.io” folder as with other PC folders and save your files there. When Internet is connected they are simply uploading to your 4s.io account and not only backed up but also synchronized (you can access them from any other computer with Internet connection anytime).
