Hibernation accelerates restart and helps save on the cloud
Deep sleep is good not only for humans, now virtual machines in CROC Cloud can hibernate too.
The operating system of an instance uses native tools to suspend it. This ensures that it seamlessly enters/exits the hibernation mode, and, in particular, fixes certain issues such as time mismatch when resuming VM operation. An important notice: RAM data is written to an attached volume so that the user retains full control over it.
To support hibernation, preconfigure the OS first and make sure there is enough space on the volume to swap RAM content, or otherwise the instance will not be stopped. For detailed prerequisites and instructions, see the documentation.
The web interface now features the Hibernation button. The hibernation mode is about to replace the previous suspension mode, which is still available and will be disabled upon at least 1-month notice.
