Compression

Backup > Compression

The Compression page specifies the compression level used to backup. Higher compression takes longer to complete a backup. Lower compression produces larger backup file sizes. The compression setting effects both folder and volume backup.

The list of machine IDs you can select depends on the Machine ID / Group ID filter. To display on this page, machine IDs must have backup software installed on the managed machine using the Backup > Install/Remove page.

Sample Compression Ratios

The table below shows the times, reduction and size of a typical Windows XP system drive (C: ), with office and other expected applications. These numbers are only a guide and will differ greatly for different types of data. MP3 or other highly compressed files will not compress much, but text or other uncompressed data will compress more.
