Backup Features - Maximize compression, minimize storage

Before your files are encrypted using your own unique encryption key, they are compressed using state-of-the-art compression technology. This compression ensures that the time it takes to do backups is shorter. And because each file is significantly smaller, you use less storage space on our servers.

Different file types tend to compress to different levels. Some files, such as multimedia files like MP3s and pictures are already compressed, so you will see little additional compression. Other files such as Microsoft Word documents and many databases can compress more than 80%. While your compression results may vary.

The following are some representative results for certain files based on actual data.

Program / File Type	Extension	Compression Savings	100 KB File After Compression
Microsoft Word Documents	.doc	80%	20 KB
Microsoft Excel Spreadsheets	.xls	75%	25 KB
Microsoft PowerPoint Presentations	.ppt	65%	35 KB
Microsoft Outlook .pst files	.pst	50%	50 KB
QuickBooks Data File	.qbw	80%	20 KB
Adobe PDF Documents	.pdf	20%	80 KB
MP3 Music Files	.mp3	0%	100 KB
