By default, the program excludes from backups files with the following extensions: .~, .tmp, and .tib.
How to add an exclusion criterion:
You can enter explicit file names for exclusion from the backup:
file.ext - all such files will be excluded from the backup.
C:\file.ext - the file.ext file on the C: disk will be excluded.
You can use wildcard characters (* and ?):
*.ext - all files with a .ext extension will be excluded.
??name.ext - all files with a .ext extension, having six letters in their names (starting with any
two symbols (??) and ending with name), will be excluded.
To exclude a folder, click Browse, select the folder you want to exclude on the directory tree,
click OK, and then click Add.
To delete a criterion, for example, added by mistake, click the Delete icon to the right of the
criterion.
3.12 Validating backups
The validation procedure checks whether you will be able to recover data from a particular backup
version, so when you select for validation on the time line…
a full backup version, the program validates the full backup version only.
a differential backup version, the program validates the initial full backup version and the
selected differential backup version.
an incremental backup version, the program validates the initial full backup, the selected
incremental backup version, and the whole chain (if any) of backup versions to the selected
incremental backup version. If the chain contains one or more differential backup versions, the
program validates (in addition to the initial full backup version and the selected incremental
backup version) only the most recent differential backup version in the chain and all subsequent
incremental backup versions (if any) between the differential backup version and the selected
incremental backup version.
This information can be helpful, for example, when you find out that a backup comprising a full
backup version and a chain of incremental ones is corrupted. To troubleshoot the backup, do as
follows. First of all validate the full backup version by selecting it on the time line, right-clicking and
choosing Validate in the shortcut menu. If it is damaged, all the backup chain will be useless. When it
is not damaged, proceed to validating incremental backup versions starting from the oldest, until you
find the culprit. All incremental backup versions made after the corrupted one will be unusable, but
you will be able to recover the data at least from the previous backup versions.
To validate an entire backup:
1. Select the backup to validate, click the gear icon to open the Operations menu and select
Validate. If the selected backup is password-protected, Acronis True Image Home 2012 will ask
for the password in a dialog box.
2. After you enter the correct password the program will start the validation procedure.
3. When the validation is complete, you will see the result in the line below the backup's box. You
can cancel validation by clicking Cancel.
