|
|
|
|
|
|
|
:Proxmox VE: The `Proxmox Virtual Environment`_ is fully
|
|
|
|
|
supported. You can backup :term:`virtual machine`\ s and

|
|
|
:GUI: We provide a graphical, web based user interface.
|
|
|
|
|
|
|
|
|
|
:Deduplication: Inkremental backup produces large amounts of duplicate
|
|
|
|
|
data. The deduplication layer removes that redundancy and makes
|
|
|
|
|
inkremental backup small and space efficient.

Why Backup?
|
|
|
|
|
-----------
|
|
|
|
|
|
|
|
|
|
The primary purpose of backup is to protect against data loss. Data
|
|
|
|
|
loss can happen because of faulty hardware, but also by human errors.
|
|
|
|
|
|
|
|
|
|
A common mistake is to delete a file or folder which is still
|
|
|
|
|
required. Virtualization can amplify this problem, because it is now
|
|
|
|
|
easy to delete a whole virtual machine by a single button press.
|
|
|
|
|
|
|
|
|
|
Backups can also serve as a toolkit for administrators to temporarily
|
|
|
|
|
store data. For example, it is common practice to perform full backups
|
|
|
|
|
before installing major software updates. If something goes wrong, you
|
|
|
|
|
can just restore the previous state.
|
|
|
|
|
|
|
|
|
|
Another reason for backups are legal requirements. Some data must be
|
|
|
|
|
kept in a safe place for several years so that you can access it if
|
|
|
|
|
required by law.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
- value of data, importance for your business, legal regulations
|
|
|
|
|
|
|
|
|
|
- restore tests. to make sure backup/restore works
