Do you mean backups? If so, having at least two backup copies of your private key is good practice: - A copy on mass storage. - A copy printed on paper (ASCII armoured) [1] Those two copies should be stored in different places to minimise risks. I would also copy/print your revocation certificate.

private-key backup
Hellow, this is my first time greeting you. I'm using GnuPG under Gnome desktop in Debian Sid. I have a question. Where is the safest place to store the private-key? Are there any best practices for this? Thanks in advance!
