Right. But with a caveat: the random number is not really random. In
fact the random generator is seeded with the node fqdn. Since this is a
constant, the generated random number won't change from run to run for a
given node.

file {
"/path/to/random": content => fqdn_rand(60)
}
Will produce a file containing a random number that will never change
for a given node.
Or if you want to manage cron resource directly:
cron {
"mycron":
command => "/usr/local/bin/backup-logical",
hour => '*',
minute => fqdn_rand(60),
}
Hope that helps,
