Both commands enable saving messages to a disk. The difference is that one specifies where to save them and the other doesn't.

Thank you so much for your fast reply. But the first one uses "syslog", does that means the same thing with logging?

syslog is just the name of the directory where to save logs.
logging persistent url disk0:/syslog size 10000000 filesize 1000000

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

You are right. Thank you so much. why do we use url in the command "logging persistent url disk0:/syslog size 10000000 filesize 1000000"?
and where is the saving location for the command "logging persistent size 10000000 filesize 1000000"?

This questions is probably best answered by Cisco IOS developers why they choose this specific keyword.

and where is the saving location for the command "logging persistent size 10000000 filesize 1000000"?
Just tested it on my ASR. If you don't specify the location, it saved my logs to flash:/bootflash/syslog

Edit: Changed tags for your question.
