And now...
Everything seems to begin to work... and begin to come to mind questions like:
Can I make some backups?
Would only the databases (all files I can restore from the databases), would weekly, but the procedure should not weigh too much on the server (some MySQL databases now weigh 60-70 MB of data and the server is small).
Maybe it would also be nice if the databases were sent somewhere, like my pc, or Yandex disk, or a gigamail, or something like that... just to be sure that if the server goes on fire them are somewhere else...
but anyway all this should not abuse server resources too much.
Then, what will be the fastest way to move a site to another server? (Always unmanaged)
I was a little bit the desire to Linode or maybe vultr (although I asked, but I did not understand if Vultr accepts adult)
For quite a while my sites will remain here, after all the effort I made, however I wonder, if I wanted to move a site I have to reload one by one all the databases via phpMyAdmin and via FTP all files?
Exist a faster, more practical and more secure way?
