Estimating Log File Disk Requirements

When you run the vbr--setupconfig command to create the configuration file and configure advanced parameters, one of the parameters is tempDir. This parameter specifies the database host location where vbr writes its log files and some other temp files (of negligible size). The default location is the /tmp/vbr directory on each database host. You can change the default location by specifying a different path in the configuration file.

The temporary storage directory also contains local log files describing the progress, throughput, and any errors encountered for each node. Each time you run vbr, the script creates a separate log file, each named with a timestamp. When using default settings, the log file typically uses about 4KB of space per node per backup.

The vbr log files are not removed automatically, so you must delete older log files manually, as necessary.
