These options are effective only for file-level backup in Windows operating systems.
In archives, store encrypted files in a decrypted state
This 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 are included in the backup and you want them to be accessed by any user after recovery. Otherwise, only the user who encrypted the files/folders will be able to read them. Decryption may also be useful if you 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). To access a file or folder encryption setting, select Properties > General > Advanced Attributes > Encrypt contents to secure data.
Preserve file security settings in archives
This 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 to read, write or execute the files for each user or user group. If you recover a secured file/folder on a machine without the user account specified in the permissions, you may not be able to read or modify this file.
To completely eliminate this kind of problem, disable preserving file security settings in archives. The recovered files and folders will always inherit the permissions from the folder to which they are recovered or from the disk, if recovered to the root.
Alternatively, you can disable recovery of the security settings, even if they are available in the archive. 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.
