Backing up data can be a daunting task to undertake especially when large data is involved. It’s more complicated when you have to decide if you are doing a full, incremental or differential backup, what to delete, what to maintain and when a lot of devices are involved. But that shouldn’t worry you, with the following questions, you will find backing up data an easy peasy task.
何時執行備份？
這是指時間範圍，指定的時間段，甚至是您應該執行備份的頻率。這個問題的答案很簡單，盡可能定期備份您的數據。手動執行此操作很煩人，大多數設備和系統都支援自動備份，您所要做的就是根據您的喜好和數據靈敏度定期安排它。此外，您應該滿足緊急備份的需求。
你應該備份什麼？
In general, you should backup important data from all your devices. That’s your computer, tablet, smartphone, and other devices that you use on a daily basis. The best thing about most of these devices, such as tablets and smartphones is that they come with proprietary cloud storage and if you don’t have vast amounts of data, you shouldn’t worry about the cost. You just need to enable the automatic backup feature and connect to a secure WIFI connection.
在哪裡存儲備份？
Backups can be regarded as a safety precaution in case the main system fails/compromised. This means you should not store your backups in your main system. You should store your back up in an isolated location away from your main system. Depending on your backup, you might want to keep some near your proximity. Backups are mainly stored in secondary storage devices, network attached storage (NAS), and lastly on the Cloud.
- 輔助存儲 – 在這個數字時代，需要考慮兩種主要類型的輔助存儲，USB 快閃記憶體驅動器和外部硬碟驅動器。USB快閃記憶體驅動器非常便攜，可以根據大小存儲大量或更少的數據。由於它非常便攜，您可能會很快丟失或放錯地方。如果使用次數過多，它也可能會丟失記憶體。另一方面，外部硬碟驅動器可以是攜帶型擕式的或固定的，它還存儲大量數據並且不容易丟失記憶體。備份在這些設備上手動完成。請注意不要丟棄這些輔助存儲設備。
- Network attached storage (NAS) – In a nutshell, this is a specialized computer server or hardware with tons of hard drives which are accessible from a network, hence convenient. With NAS, you can store vast amounts of data, and you can configure automatic backups. NAS has some drawbacks such as it’s expensive, needs to be configured, and it requires a higher level of security.
- Cloud storage – This can be seen as some of NAS, or somebody’s computer that’s is very portable and accessible via the internet. In cloud storage, you need to make sure the cloud provider has implemented proper levels of security and your connection to the cloud is secure.
如何備份？
如果手動完成，這是最難的部分。但是，由於大多數備份都是自動化的，因此您的系統可以通過正確的配置為您完成所有操作。使用備份軟體，不會出錯。
Lastly, you should always ensure that your backups are secure regarding storage, transfer, and access. For instance, when accessing your cloud backup/NAS, use a secure tunnel, a VPN connection does the job.
