With GPG a symmetric key is always used for encryption, but in publicOn Mon, Oct 19, 2009 at 8:47 AM, Chris Poole <address@hidden> wrote:

key mode the symmetric key is random and is stored using the public
Because the key should be very small compared to your data the
performance difference should not normally be measurable.
The advantage of public keyed backups is immense: it means your backup
process can run without any knowledge of the key, the key is only
needed for recovery.
