have you installed backup application on ESXi? or running backup application as VM/Appliance on ESXi Host?
Consider configuring Remote syslog server and forward ESXi and backup application logs to Syslog server.
I installed Backup application in ESXi.
I don't like the idea of mixing the backup log with syslog.
I don't like the idea of using a remote syslog server as this will require more hardware and money.
I posted this question a long time ago but only one person suggested a work around which is not satisfactory for my case.
Requested a suggestion to place the question in other forum in the attempt to get more help, but I have not receive not even that.
here I am back with another workaround as there is no official solution.
I did some more research on this. ESXi usages VMsyslogd service for logging and log rotation.
configuration files -
Inside /etc/vmsyslog.conf.d/ directory there are different configuration files for specific service/application log rotation.
You can try to create your own configuration file with new application details and with similar syntax to any old file. save it as .conf
Once you are done, restart ESXi server.
Monitor your application log dir to see if log rotation is happening or not.
I have not tested it, So I would suggest you to test it before implementing it in prod.
I am not sure if such configuration will be even supported by VMware, so better you check with VMware Support.
Also, you can post this question on backup software vendor site if they have any solution for this.
Another way of doing this - Create shell script which will rotate logs.
Sounds promising but I cant test it. I do not have a Development ESXi Server available at this moment so I will have to wait for another client to make tests before getting it on production.
I found a script that does the job to make versions of the log but the old versions are not removed so the log will not grow indefinitely but the count of files will. This is OK but not enough as cant let the ESXi unattended. I am not a bash programmer so I do not know ho to modify it to remove the old files after a certain number of them.
