Yes and no. It's stored in memory until a process writes it to disk.
Basic sar data is really just reading /proc for numbers. But that is of
course just in memory data. To store it requires a system process that
collects it. That usually runs in cron or as a daemon.

On different VM hard resets, I've noticed that sar data is lost. On
one reset, all data prior to the reset (0000-reset) was missing, on
another all data after (crash-2350) was missing.
Any ideas why? Is the data stored in memory?

Every time you stop a school, you will have to build a jail. What you
gain at one end you lose at the other. It's like feeding a dog on his
own tail. It won't fatten the dog.
