When running a backup job, you may see the following "Info" and / or "Errors" in the backup reports
Error="ChunkedOutputStream.FlushData.execute] Failed to flush buffer
(directory_path\vm_name-flat.vmdk) to this destination.
Error='java.io.IOException: [FastPipedOutputStream.write]
FastPipedOutputStream has been closed by the reading
thread.', caused by [IOException][FastPipedOutputStream.write]
FastPipedOutputStream has been closed by the reading thread."
And / or
Failed to upload file "XXXXXXXXXX/blocks/2019-01-13-13-36-00/0/000002_000025.bak", will retry after 30 seconds (# of retry: 1/10)
This can be caused by an unstable network connection between the SDSL Backup Client and our backup Server
To resolve this please try fine tuning the performance of the backup client by following the steps below:
1. Open afc.opt found in C:\Program Files\SDSLBusinessCloudBackup
2. Find the line com.ahsay.afc.bfs.cloud.ChunkedOutputStream.retry= and add 20 to the end
3. Find the line com.ahsay.afc.io.ReadAheadInputStream.timeout= and add 300 to the end
4. Find the line com.ahsay.afc.bfs.cloud.ChunkedOutputStream.upperSleepLimit= and add 5 to the end
So the 3 lines should look like this
com.ahsay.afc.bfs.cloud.ChunkedOutputStream.retry=20
com.ahsay.afc.io.ReadAheadInputStream.timeout=300
com.ahsay.afc.bfs.cloud.ChunkedOutputStream.upperSleepLimit=5
Save and exit the file
Now try rerunning the backup
