The best: Acronis Cloud (p. 28) or an external hard disk.
Refer to Deciding where to store your backups (p. 35) for details.
How many backup versions do I need?
In most cases, you need 2-3 backup versions of your entire PC contents or your system disk, with a
maximum of 4-6 (see above for information about when to create backups). You can control the
number of backup versions by using automatic cleanup rules. Refer to Custom schemes (p. 56) for
details.
Remember, the first backup version (the full backup version) is the most important. It is the biggest
one, because it contains all data stored on the disk. Further backup versions (the incremental and
differential backup versions) may be organized in different schemes. These versions contain only
data changes. That’s why they are dependent on the full backup version and why the full backup
version is so important.
By default, a disk backup is created by using the incremental scheme. This scheme is optimal, in most
cases.
For advanced users: it is a good idea to create 2-3 full backup versions and store them on different storage
devices. This method is much more reliable.
