Task Properties: Compression

Check "Use compression" to save space on the destination drive. GrandBackup has a built-in ZIP-compression module, but you can use any external data-compression utility, like RAR or CAB. GrandBackup will launch such external utilities by appropriately configured commands.

Archiver - select the compressor to be used in the Task. Press Settings... to configure an external compressor.

Tip:
To use the built-in ZIP module, no additional utilities or settings are required, just leave "Built-in ZIP compressor" selected in the drop-down list. The files will be compressed in a PKZIP-compatible format and can be extracted by utilities such as PKUNZIP or WinZip.

Compress each file in a separate archive - Make as many archives in the backup as there are files in Source

Compress all files into a single archive - Put all the files in Source into one large archive in Destination

Archive name ________ - Specify the name of the Destination archive

Archive password - Enter a password to protect the compressed archive. You will need this password to extract the files.

Caution:
If you forget the password it cannot be recovered.

Compression level - Select the degree of compression, on a scale of 0 to 9, where 0 to 1 corresponds to minimum, 2 to 7 to medium, 8 to 9 to maximum compression (see Preferences: External Compressors).
