initrd When the device boots, initrd first moves system time forward to match the time initrd was built. snap-bootstrap · snap-bootstrap is the main executable run during the early initrd boot stage. It will itself move time forward to that of the most recent assertion it trusts, signed with Canonical’s key. user-space After the snap environment is re-executed and the boot process moves to user-space, systemd’s timesyncd will attempt to update the system time: on devices with an RTC System time is moved forward to match that of the on-boar ...
Any recovery system created using the API is derived from a device’s current model. Each required snap in the model will be a part of any newly created recovery system. Optionals snaps in the model will be included if the snap is already installed, or if the snap is required by any validation sets that are provided. Snaps within a new recovery system will follow whatever constraints may be defined by any provided validation sets. Additionally, because a model can reference validation sets, those validation sets will also be considered. ...
Installing Ubuntu Core 2x on a device with a TPM (such as an Intel NUC, or QEMU with emulated TPM) can sometimes result in a stalled installation and a TPM is in DA Lockout Mode error, as shown in the following example install log: This error typically means the TPM has been locked to protect the system against potential dictionary attacks (DA) and the TPM needs to be cleared before the Ubuntu Core installation will proceed. To clear the TPM on hardware, boot a classic Ubuntu system (such as a live version of Ubuntu 20.04 LTS from USB storage) ...
The following recovery functions are currently available: ; Install mode / factory mode: initialise the device from an onboard system image ; Run mode: restarts normally and runs the boot process ; Recover mode: reboot into recovery mode for data retrieval ; Factory reset: erase system data and initialise the device to its factory state
These recovery modes can be accessed in three different ways: ; Boot into the system mode selection menu · Start or reboot the device with the ‘1’ key held on a connected keyboard ; Snap reboot · Run snap reboot on the device with either --recover or --install arguments. ; Snapd REST API · Use the REST API to call either the recover, install, factory-reset or reboot functions.

The demand for cloud data storage in all organizations is growing, in this whitepaper you can learn how the open-source software-defined storage system, Ceph, can fit into the landscape of enterprise storage deployments, and help you keep pace with the demands on your storage infrastructure. A software-defined storage (SDS) system is a type of storage solution that abstracts away the hardware used to build the system, unlike traditional appliances that are tied to the underlying hardware supplied by the vendor. This means that a user of SDS can ...
Why? - Why are you protecting yourself against disaster? Does it matter if you lose data? What losses will you suffer ($$$)? ; What? - What are you going to backup? Your entire hard drive or just some of the data? ; When? - When is the best time to backup your system? How often will you perform a backup? When will you use full backups and incremental backups.
A Disk based system in the same data centre would provide a rapid means of recovery from malicious or accidental deletion of data, but is unlikely to help in a true site-wide disaster...
