Save settings between sessions: If enabled, the changes made in this dialog will be saved between sessions with restore program.
Overwrite options
These options determine file overwriting during restoration. Options Restore into existing directories and Overwrite older/newer files can be set to Ask, Overwrite/Restore or Skip. Overwrite and Restore mean that corresponding files will be restored. The files will be skipped with Skip. Ask means that a dialog will appear to decide whether a file should be restored or skipped. Ask is the default.
Restore into existing directory:
When a file is going to be restored in a directory which already existed before restoration, this will be utilized. File will be restored, skipped or Ask-dialog will be shown, depending on how option is set.
Protection against restoring into existing directory seems not very important, because no files are overwritten then. But it can produce a mess on the hard disk. For an example, a total failure of hard disk occurs. Before the full restore is done, maybe you want to install the latest versions of operating-system and network software, which are newer than the versions on hard disk before the crash. During full restore you will be warned, if files would be copied into directories with new operating-system-version (assuming option is set on Ask).
Overwrite older files:
Overwriting existing files during restore is delicate. Restore program has double protection against unwanted loss of data during restore. First, copies of overwritten files can be made. Secondly restore of files existing on PC is controlled with options Overwrite older files: It is used, when a file existing on PC has an older date and time. It can be set to Overwrite or Skip file or to Ask.
Overwrite newer files:
This is a similar case as Overwrite older files. If file on PC has a newer, or the same date and time, option Overwrite newer files is used. Overwriting newer files is more dangerous than overwriting older files. For this reason, option Overwrite newer files may only be set equal or more restrictive than Overwrite older files. An invalid combination would be, for example, Overwrite for Overwrite newer files and Skip or Ask for Overwrite older files.
Make temp. copies of overwritten files:
Restore of existing files on PC is managed with restore options Overwrite older (newer) files. As an additional protection, copies of the files on PC can be made before they are overwritten. Copies are in the same directory as their originals, and differ from their original by a slight modification of filename. Extension part of the file name, namely the part after "." sign is replaced by .$$1. If a file with the new name exists already, extension will be set to .$$2 etc.
These files are kept until restore program is quit or until a new restore-operation is started. At that time, a dialog will be shown and one can decide if the file copies should be kept or deleted.
Copies of overwritten files are also used to undo a restore-operation.
Please note that copies can neither be made for registry files nor for locked files which will be replaced at next reboot. Therefore Undo operation can not be done for these files.
Locked files
This option applies to files, which can not be restored, because the file on PC with equal name is locked, and therefore can not be overwritten normally. It also applies to files whose necessary permissions or access rights are missing for restore. Files will either be skipped or restore will terminate with error message.
Restore locked files and registry at reboot:
With this option, even locked files can be restored. The restoration will be done in two steps: First the files will be restored to temporary files in the same directory. Then, replace commands will be put in System registry. At next reboot, the system will automatically replace the locked files with the restored ones. This option must also be set if registry files are to be restored. The option requires restore privilege.
Full restores of running systems are now possible. It is not necessary to restore the system to a different disk-drive and change disks afterwards.
Security
These options are related to Windows 2003/2000/NT/XP security. If Use restore privilege is set, restore privilege will be used (if user has it) to restore the files, which allows restoration of all files independent from their protection. The options Restore files owners / groups / permissions / auditings, specify the parts of each file's or directory's security description which will be restored. Restoration of files auditings requires Restore privilege.
SQL
Options for restoration of SQL Server databases: Don't recover restored SQL databases. If full backups, differential and or incremental parts of SQL database are restored together, all must be restored in unrecovered state, only the last one is restored recovered, for database to become usable again. If this option is turned on, SQL database is restored unrecovered, and further restore operations can be done on the database.
Exchange
Options for restoration of ESE98 (Exchange Server 2000/2003 databases): Don't recover restored Exchange databases. Leaves database in unrecovered state, so further restore operations can be done on the database. In this case, Restore Log path will be shown in Display Window 'Messages'. This Restore Log Path must be remembered for further Restore operations. Reopen previous non-recovered Restore must be set for the later restores. Specify Log path shown during first restore operation. Don't recover restored Exchange databases must be set for all but the last restore operation. Usually these options need not be used. It is best to select entire database and restore it in a single run. These options do not apply if Exchange Server 2003 was backed up under VSS.
Option for restoration of Exchange 5.5 Server: Don't delete database files before restore (Exchange 5.5). If specified, the Backup Logs already stored will not be deleted before the restore. Per default the Logs since latest backup should not be applied during restore, so they are deleted.
Active Directory and Certificate Services
Don't delete database files before restore. If specified, the Backup Logs already stored will not be deleted before the restore. Per default the Logs since latest backup should not be applied during restore, so they are deleted. This option is not used when restoring from a VSS System State backup.
SYSVOL / File Replication NtFrs
When restoring replicated data sets, mark the restored data as the primary data set.:Performs a Primary Restore. Ensures that restored File Replication service (FRS) data is replicated to your other servers. Please see your Windows or online documentation for more information on Primary and Authoritative restore of Windows Domain controllers, and NTDSUTIL utility. This option is not used when restoring from a VSS System State backup.
SharePoint Portal Server
Restore full-text indexes to original location. If specified, the SharePoint Portal Server 2001 full-text indexes are restored to original location during backup. Otherwise they are restore to currently defined location. This corresponds to option /o of MSDMBACK-command.
Compare
Options for compare run: Compare Registry keys If set, when registry hive is to be compared, all registry keys will be compared, and all changes will be listed. This can be useful to detect changements in registry.
