So, I'm now restarting the servers and doing disk maintenance in one of them that had some errors in one of the disk partitions.
Lately (in the last months) these power failures have happened from time to time.
I have un UPS but it can only handle the computers for the necessary time for shutdown. I need to be able to buy more batteries so that it can run longer.... And I've been looking also for a power generator so I could, in case of a power failure, run on the UPS for a while as the generator starts and then be able to run for hours independently of the outside power distribution....
But is has a high cost and I can't afford it right now... :-(((((
Well, we'll se what will be possible until the end of the year....
