Pre/post commands
You can specify commands or batch files to be executed automatically before and/or after the backup
procedure. For example, you may want to remove some temporary (.tmp) files from the disk before
starting backup or configure a third-party antivirus product to be used each time for scanning the files
to be backed up before the backup starts. Click Edit to open the Edit Command window where you
can easily input the command, its arguments and working directory or browse folders to find a batch
file.

Compression level
The preset is Normal.
Let's consider such an example - you need to backup to a USB stick some files with a total size
comparable to or exceeding the USB stick's capacity and want to make sure that the stick
accommodates all the files. In this case use the Maximum compression for the files to be backed up.
However, you should take into account that the data compression ratio depends on the type of files
stored in the archive, for example, even the Maximum compression will not significantly reduce the
backup size if it contains files with already compressed data like .jpg, .pdf or .mp3. It does not make
any sense to select the Maximum compression for such files because in this case the backup
operation will take significantly longer and you will not get an appreciable reduction of backup size. If
you are not sure about the compression ratio of a file type, try to back up a couple of files and
compare the sizes of the original files and backup archive file. A couple of additional tips: generally,
you can use the Normal compression level, because in most cases it provides an optimal balance
between backup file size and backup duration. If you select None, the data will be copied without any
compression, which may significantly increase the backup file size, while making the fastest backup.

Archive protection
The preset is no password.
Suppose you have some files with sensitive information, for example, your tax return, which you need
to back up. Acronis True Image Home can help you protect your sensitive information from getting
into the wrong hands. The simplest (and the least secure) way is protecting your backup with a
password. Let's remind you that to make a password more difficult to guess, it should consist of at
least eight symbols and contain both letters (upper and lower case, preferably) and numbers. If you
think that a password will not give you sufficient security, use encryption for your backup. Acronis
True Image Home allows encrypting backup files with the industry-standard AES cryptographic
algorithm. A 128-bit encryption key is sufficient for most applications. The longer the key, the more
secure your data. However, the 192 and 256-bit long keys significantly slow down the backup
to back up. Acronis True Image Home can help you protect your sensitive information from getting
