New server setup, best practice?

Tue Aug 16 04:27:15 UTC 2016

How:
find /path/to/files* -mtime +5 -exec mv {} \; /path/to/destination 
That would be one way.
Where: Depends on the situation. Sometimes it’s from SSD to HDD, sometimes it’s from local HDD to remote NAS using NFS or CIFS.

Best? I like CentOS 5 best just because it remained pretty much the same for over 10 years.

That being said, CentOS 7 would be the way to go; you just need to know where to put things.
