8.1.2 What data can I back up and recover?
You can back up files, volumes, disks, or the entire physical machine as often as you wish. Unlike
most online backup solutions, Acronis Backup & Recovery 10 Online enables bare metal recovery
directly from the online storage. Files can be recovered from disk-level backups as well as from file-
level backups.
For information about backing up virtual machines see "How to back up virtual machines to the
online storage? (p. 380)"
8.1.3 How long will my backups be kept in the online storage?
Your backups remain in the online storage until you delete them or until the subscription expires.
Recovering data from the online storage is possible for 30 days following the subscription expiration
date.
For effective use of the storage space, you have the option to set up the "Delete backups older than"
retention rule.
Example
You might want to use the following backup strategy for a file server.
Back up the critical files twice a day on a schedule. Set the retention rule "Delete backups older
than" 7 days. This means that after every backup the software will check for backups older than 7
days and delete them automatically.
Run backup of the server's system volume manually as required. For example, after the operating
system updates. Manually delete the backups that you do not need.
8.1.4 How to secure my data?
Backups can be encrypted using the Advanced Encryption Standard (AES) cryptographic algorithm
and the password you set. This guarantees that your data is not accessed by anyone else.
8.1.5 How to back up virtual machines to the online storage?
Use either of the following methods or both.
Install Acronis software onto the virtualization host
This approach comes in handy when the virtualization product installed on the host server is VMware
ESX(i) or Windows Server 2008 with Hyper-V or Microsoft Hyper-V Server.
You will be able to back up entire virtual machines or their volumes using a single subscription for
virtual machines. The subscription applies to all machines hosted on the host or to the entire vCenter
cluster. File-level backup and recovery is not possible for virtual machines, but is possible for a
Windows host.
Installing the software, backing up, and recovery are described in the Quick Start Guide for Acronis
Backup & Recovery 10 Virtual Edition. When installing Acronis Backup & Recovery 10 for online
backup only, you do not need to enter a license key during installation.
