After upgrading from a release prior to 03.02.01 build 3, all newly created
S3CLOUD Resources will get the larger segment size automatically.
While performance of existing Resources will increase immediately with the
installation of the new release, additional increases can be had by manually
updating the segment size of previously created Resources.
Edit the file /usr/lib/edge/config/devices.def using a text editor like vi or
- Search for "TYPE s3cloud".
- Within each s3cloud entry, change "SEGMENT_SIZE=51200" to
- Exit the editor and type "edge.tape". This will re-compile the Resource
database in BackupEDGE.
Do not exceed 512000 as memory usage issues will result. BackupEDGE will still
deal with older backups just fine, but newer backups will have segments 10
times larger, which will also reduce segment overhead.
If you have a system with 1GB or less RAM, try setting SEGMENT_SIZE to 256000
or 128000. Perform multiple backups to see which SEGMENT_SIZE has the fastest
net backup and verify time.
