Configuration file persistence on ESXi host

Jump to solution

Maybe it is a really simple/stupid question but how persistent is a modification of a system configuration file or any other configuration file on an ESXi hypervisor (especially ESXi 6.0)? Will the modification removed or reverted after applying a host patch or reboot?

For example:

If I made some change in /etc/vmware/hostd/config.xml and apply a new patch to the host or rebooted the host will these changes get lost? Or is there any scenario where these changes would be reverted/removed?

Kind regards,

Ybbom

ESXi regularly runs a script to make any changes persistent, by writing them to the bootbank. I think it's once every hour but I may be wrong on that. You can also do this manually by running:

/sbin/auto-backup.sh
