You cannot create Droplets in certain datacenters due to limited capacity. If you have snapshots in a limited capacity datacenter, transfer them to another datacenter to create Droplets from them.
You cannot downsize a Droplet from a snapshot. Data is not always stored sequentially in memory, so reducing the size of a disk can result in data loss or corruption.
Snapshots of Droplets are a best estimate based on the disk usage. Snapshots of volumes operate at the block storage level, so the snapshot size may not match what the filesystem reports.
To rename your Droplet, change the Droplet’s name in the control panel, then change its hostname from the command line using hostnamectl or by editing /etc/hostname and /etc/hosts.
Snapshots do not retain the IP address of the Droplet they were created from, but you can use reserved IPs to assign the same address to new or redeployed Droplets.
High RAM or CPU usage is normally the result of applications or kernel processes on the Droplet. You can monitor high CPU usage processes on the Droplet and stop them if necessary.
Problems during SSH protocol initiation include the client suddenly getting dropped or closed, the client returning errors about cipher negotiation, or issues with an unknown or changed remote host.
Problems with SSH shell environments include being unable to fork a process, the system reporting it’s not a valid shell, or issues reaching the home directory.
