Result: you have a single up-to-date full backup version

Required storage space: minimal.

3.10.1.2 Version chain scheme

This backup scheme differs for disk backup and file backup types.

Disk backup version chain

At first the program creates the 1st full backup version. The version will be kept until you delete it

manually. After that, according to the specified schedule (or when you run backup manually) the

program creates: 1 full and 5 differential backup versions, then again 1 full and 5 differential backup

versions and so on. The versions will be stored for 6 months. After the period the program analyzes if

the oldest backup versions (except the 1st full version) may be deleted. It depends on the minimum

number of versions (eight) and version chains consistency. The program deletes the oldest versions

one by one after creating new versions with the same backup method (for example, the oldest

differential version will be deleted after creation of the newest differential version). First of all the

oldest differential versions will be deleted, then - the oldest full version.

Backup scheduler setting: monthly

Result: you have monthly backup versions for the last 6 months plus the initial full backup version

that may be kept for a longer period.

Required storage space: depends on the number of versions and their sizes

File backup version chain

According to the specified schedule (or when you run backup manually) the program creates: 1 full

and 6 incremental backup versions, then again 1 full and 6 incremental versions and so on. The

versions will be stored for 1 month. After the period the program analyzes if the oldest backup

versions may be deleted. It depends on the version chain consistency. To keep the consistency, the

program deletes the oldest versions by chains "1 full + 6 incremental backup versions" after creating

a new analogous version chain.

Backup scheduler setting: daily

Result: you have backup versions for every day of the last month

Required storage space: depends on the number of versions and their sizes

3.10.1.3 Custom scheme

Acronis True Image Home 2011 Netbook Edition also allows you to create your own backup scheme.

The scheme can be based on creating full, differential or incremental backup versions.

So first of all select one of the backup methods in the appropriate box.

 Full (p. 35)

Select this method if you want to create only full backup versions.

 Differential (p. 35)

Select this method if you want to create backup chains containing only full and differential

backup versions.
