I updated my webserver with Ubuntu 18. Then I decided to upgrade to Ubuntu 19. But first I needed a backup of WordPress. I decided on “UpdraftPlus“. I backed up my WordPress data and moved it to a thumb drive. Then for the move to Ubuntu 19. It failed. After about 1.5 hours the process just hung. I did a hard reset and that was it. I should also point out that I had no power to the PC internals – MB, disks so I am assuming that shortly after I started the upgrade the Power supply failed. Can’t complain: 10 years x 24 hours a day. Took me 4 days to rebuild the box. I had good Readme.files but many of the commands in them were no longer valid because mysql, apache2 had changed their syntax for their commands/statements. Lots of Googling. Anyway once I got the box configured to support WordPress and got WP downloaded and installed I once again downloaded the UpdraftPlus plugin for backups/restore. I moved the backup files from the thumb drive to the newly build PC and using UpdraftPlus restored the data. PERFECT!!! About 2 minutes and my WordPress blog was recovered vs. 4 days of rebuilding a PC. UpdraftPlus is definitely a winner.
