Due to \r characters not being filtered off replicas, logs can grow too much in replicas scheduled in the ESXi cron for big VMs.
It will be fixed in version 188.8.131.52
If your logs are growing too much you can use the following workaround in the job file:
Prepend | sed '/\r/d' to the log redirection line.
Last line in the log would look like this for an installation in the default location (/scratch/XSI/XSIBackup-DC)
| sed '/\r.*::: detail/d' >> /scratch/XSI/XSIBackup-DC/var/log/xsibackup.log 2>&1
