Unison is a file-synchronization tool for OSX, Unix, and Windows. It allows two replicas of a collection of files and directories to be stored on different hosts (or different disks on the same host), modified separately, and then brought up to date by propagating the changes in each replica to the other.
Sia is a decentralized storage platform secured by blockchain technology. The Sia Storage Platform leverages underutilized hard drive capacity around the world to create a data storage marketplace that is more reliable and lower cost than traditional cloud storage providers.
È arrivata anche sulla stampa mainstream la notizia delle vulnerabilità chiamate Meltdown e Spectre dei processori Intel, AMD e ARM.
Senza entrare nel merito della gravità o meno della questione, riprendo un interessante commento "collaterale" di Alan Cox, guru del kernel Linux, riguardo ad una "check-list" per capire se siamo preparati alla eventualità di dover gestire alcune attività "di emergenza" che potrebbero essere di non semplice semplice realizzazione in caso non ci si fosse pensato preventivamente;
So keep backups, test they work and have an up to date plan for what to do if/when your machine gets hit by something evil (or for that matter gets killed by coffee, cats, fire or other natural disasters).
Do you have the phone number to cancel your bank cards if you have no computer or internet ?
Do you know how to restore a backup on a new machine ?
If you are dealing with proprietary software do you have copies of any license keys ?
What plan do you have to change passwords on accounts and how will you do it with no PC of your own working?
TimeShift for Linux is an application that provides functionality similar to the System Restore feature in Windows and the Time Machine tool in Mac OS. TimeShift protects your system by taking incremental snapshots of the file system at regular intervals. These snapshots can be restored at a later date to undo all changes to the system.
Snapshots are taken using rsync and hard-links. Common files are shared between snapshots which saves disk space. Each snapshot is a full system backup that can be browsed with a file manager.
TimeShift is similar to applications like rsnapshot, BackInTime and TimeVault but with different goals. It is designed to protect only system files and settings. User files such as documents, pictures and music are excluded. This ensures that your files remains unchanged when you restore your system to an earlier date. If you need a tool to backup your documents and files please take a look at the excellent BackInTime application which is more configurable and provides options for saving user files.
TimeShift is a system restore tool for Linux. It provides functionality that is quite similar to the System Restore feature in Windows or the Time Machine tool in MacOS. TimeShift protects your system by making incremental snapshots of the file system manually or at regular automated intervals.
To provide an insight into the quality of software that is available, we will look at 34 outstanding open source backup tools that you can use on Linux servers or systems. There will be something of interest for anyone who attaches any importance to their hard work.
