64 Copyright © Acronis, Inc., 2000-2009Fixed sizeEnter the desired file size or select it from the drop-down list. The backup will then be split intomultiple files of the specified size. This comes in handy when creating a backup that you plan to burnto multiple CDs or DVDs later on. You might also want to split the backup destined to an FTP server,since data recovery directly from an FTP server requires the backup to be split into files no more than2GB in size.3.3.1.14. File-level securityThese options are effective only for file-level backup in Windows operating systems.In archives, store encrypted files in a decrypted stateThis option defines whether to decrypt files before saving them to a backup archive.The preset is: Disabled.Simply ignore this option if you do not use the encryption. Enable the option if encrypted files areincluded in the backup and you want them to be accessed by any user after recovery. Otherwise, onlythe user who encrypted the files/folders will be able to read them. Decryption may also be useful ifyou are going to recover encrypted files on a different machine.File encryption is available in Windows using the NTFS file system with the Encrypting File System (EFS). Toaccess a file or folder encryption setting, select Properties > General > Advanced Attributes > Encrypt contentsto secure data.Preserve file security settings in archivesThis option defines whether to back up NTFS permissions for files along with the files.The preset is: Enabled.When the option is enabled, files and folders are saved in the archive with the original permissions toread, write or execute the files for each user or user group. If you recover a secured file/folder on amachine without the user account specified in the permissions, you may not be able to read ormodify this file.To completely eliminate this kind of problem, disable preserving file security settings in archives. Therecovered files and folders will always inherit the permissions from the folder to which they arerecovered or from the disk, if recovered to the root.Alternatively, you can disable recovery (p. 74) of the security settings, even if they are available in thearchive. The result will be the same - the files will inherit the permissions from the parent folder.To access file or folder NTFS permissions, select Properties > Security.3.3.1.15. Media componentsThis option is effective for both Windows and Linux operating systems, when the backup destinationis removable media.
