Professional Edition Features

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

Compression Type

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.

Compression Quality

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.
