I have a backup in an external HDD, and I wanted to make a copy of it for security...which is the best way? As far as I ca see, I can copy the backup folder to another HDD, or I can make another backup in Acronis with the same options of the original one, it it there another option? Like configuring Acronis automatically to make the same thing in another location?
Of course, you can always manually/using a script make a copy of the files. For safety you can verify by comparing hashes (MD5/SHA-1) of the copy and original backup files.
