Attix5 Pro can be configured to back up large file counts in a relatively short time period by changing the way that small files are handled. The ability to achieve these backup speeds is dependent on the environment, and is easier to achieve within a LAN speed environment where compression is not essential.
Before changing any settings, it is recommended to first increase the service memory as detailed here: http://v6.attix5.com/kb/?View=entry&EntryID=146.
Tests were conducted on two servers with the following specifications:
SERVER1 contained 6 267 660 files and SERVER2 contained 1 748 432 files. Before the settings were modified for large file counts, backups would take approximately 24 hours (and sometimes many more) to complete. After the settings were optimized for large file counts, the backup times dropped significantly, which can be seen in the table below.
The settings used to achieve this massive improvement can either be configured by profiling, or added into the a5backup.properties file for individual Backup Clients.
Note: Backup Transmission Queue In-memory Limit, Background Transmission Queue Capacity and Disk Usage have been deprecated from the V7 SP Console. This functionality can still be used on V6 Backup Clients backing up to V7 Storage Platforms by configuring the options on the Backup Client side. V7 Backup Clients feature Streaming Backup functionality which effectively replaces the background transmission queue. Please enable Streaming Backup to use this functionality.

You may also want to investigate the NTFS change journal as using this decreases the amount of time taken to build the backup selection list (after the first backup, and if the selection has not changed). Details of setting this can be found here: http://v6.attix5.com/kb/?View=entry&EntryID=24.
