This section describes the settings associated with the Professional version of StorageSync.  

  Activity: Backup operations 

  Settings: No compression (default) 

Compress to single archive 
Compress to multiple archives 

Compression Type lets you specify whether file compression is turned on during back up 
operations. Compression uses a proprietary algorithm to back up the maximum number of 
files onto the least amount of space on the target media drive.  

By default, No Compression is enabled. Compress to single archive merges all backup files 
into one compressed archive file. Compress to multiple archives keeps multiple archived 
versions of the backup files. 

 

Selecting Compress to single archive disables StorageSync’s File Revisioning 
feature. It also increases processing time for restoring and deleting files. For this 
reason, we recommend you use Compress to multiple archives when you require 
compression for backing up data. However, if you prefer to encapsulate all the 
backed up files into a single archive for ease of transfer (e-mail, FTP, or via media 
drive), we recommend that you use full backup and use Compress to single 
archive. This combination will effectively take a snapshot of your backup job in 
one archive. 

 

  Activity: Backup operations 

  Settings: Nine levels, from low (default) to high 

If you select Compress to single archive or Compress to multiple archives under 
Compression Type, you can use the Compression Quality bar to choose from nine 
compression selections. By default, Low is enabled. Low provides the least amount of 
compression, while High provides maximum compression.

Using high compression minimizes the amount of space consumed on the target 
media drive, but increases the backup time.
