We have a number of production sites (mostly on one AWS instance) that require an update of Drupal Core from 7.34 to 7.35.
I have tested an update on one development instance using the following drush command:
drush up drupal
I also have tested an update on another development instance using a patch from this site: http://fuerstnet.de/en/drupal-upgrade-easier The commands were:
patch -p1 --dry-run < drupal-7.34-to-7.35.patch
patch -p1 < drupal-7.34-to-7.35.patch
There are no db updates involved.
It seems to me that on the one hand, drush backs up the core files but on the other hand, the patch is faster.
So, which would be safer?
