• Data and file types

The type of data being backed up or restored can affect performance. Typically, small files

incur greater overhead in processing and access than large files. Equally, data that is not

compressible will always limit the speed at which the drive can write/read data. You will

achieve no more than native rates with uncompressible data.

Examples of files that compress well are plain text files, spreadsheets; those that compress

poorly are those that are either compressed as part of their format (such as, JPEG

photographic files) or stored as compressed (such as, .ZIP files or .gz/.Z files on Unix

platforms).
