You can define the block size of data that Arcserve Backup migrates to Eucalyptus-based cloud storage media. This capability is useful in that you can define a block size that suits the capabilities of your network. For example, when the network bandwidth is high, you define a higher block size. Conversely, when the network bandwidth is low, you define a lower block size. Keep in mind, when communication between the source server and the Eucalyptus-based cloud storage media fails, Arcserve Backup retransmits the chunks of data that were transmitted previously after communication resumes.
The default chunk size is 10 MB. You can define the value of the chunk size as from 1 MB to 50 MB.
Follow these steps:
$ARCSERVE_HOME\CCI\Config\CCIConfig.ini
[Eucalyptus_Config] ChunkSize=1048576
Examples:
5 MB = 5242880 bytes
25 MB = 26214400 bytes
