Say you're about to cancel a VPS, but first you need to copy its contents (source<\/em>) over to another server (destination<\/em>).<\/p>\n

We will be using rsync<\/code>. Note: rsync will keep the original timestamps for both files and folders, so that's good.<\/p>\n

General idea:<\/p>\n

rsync --params source destination<\/code><\/pre>\n
Because we will copy the whole source<\/em> VPS, we will have to do it using the root<\/code> account to avoid permission errors. Since most likely you won't be able to SSH into your source<\/em> with root from any other server, instead you will have to su<\/code> to root on the source<\/em>, and then SSH into the destination<\/em>. Could be any account on the destination<\/em>, but lets say it's admin<\/code>.<\/p>\n
Updated general idea:<\/p>\n
rsync --params \/ admin@example.com:\/folder<\/code><\/pre>\n
Start by configuring SSH access from the source<\/em> server to the destination<\/em> server.<\/p>\n
    \n
  1. Elevate to root<\/code> on the source server: su -<\/code> or sudo su -<\/code><\/li>\n
  2. Display and copy the public key of the root account: cat ~\/.ssh\/id_rsa.pub<\/code><\/li>\n
  3. Go to the destination server. Log in to the admin<\/code> account. Open it's ~\/.ssh\/authorized_keys<\/code> for editing and put the copied key in there.<\/li>\n
  4. Test the connection on the source<\/em> server: ssh admin@example.com -p 2222<\/code><\/li>\n<\/ol>\n
    Copying from this server to another<\/p>\n
