Advanced Settings

 

 

The settings on the 'Advanced' pages apply to the current image or backup definition. To globally change the defaults for all future images or backups take the 'Reflect Defaults' option. From the main menu choose 'Other Tasks' then 'Defaults'.

 

 

For incremental and differential images or backups the only property available is 'Disk Space Management'. All other properties are set by the image appended to.

Compression

 

Compression Level

Select the compression (if any) to use for this image file. A Typical compression factor is about 50% at medium compression setting. Increasing the compression level will increase the amount of time required to backup and restore the image.

 

 It is only recommended that you select the 'High' compression setting if you are backing up to optical CD /DVD drives. This is because the relatively low transfer rate of the data means that the compression level will not compromise performance.

 

 

File Size

 

 

Automatic

Let Reflect determine the maximum image file size. The maximum file size will be determined by the file system and the available space on the destination drive. For FAT32 the maximum file size is 4GB, for NTFS and optical drives (CD / DVD) the file size is determined by the amount of free space on the drive. If there is no more free space on the drive then you are prompted for a new location for the remainder of the image data. If the resultant image file is larger than 4GB and you are saving to a FAT32 location then the image file is split into multiple files and the file number (at the end of the image file name) is incremented.

 

Enter a fixed size

You can enter a fixed number of MB or GB for the maximum file size. This is useful if you want the speed of a local hard disk for the initial backup, but later want to transfer the image files to CD / DVD where space per disk is limited. As soon as the file size is reached a new image file is created and the file number (at the end of the image file name) is incremented.

 

Password

 

 

If a password is entered, then the image file cannot be restored or browsed without entering the password first. For security reasons the password is not stored with the file, only an MD5 hash value of the password is stored.

 

The password can be up to 256 characters in length, any combination of letters and numbers and is case sensitive.

 

If you forget your password, there is no way of recovering the image data. You should make sure that you always choose a password that you, and only you, can remember.

 

AES Encryption, allows you to specify up to 256 bit encryption, making your data totally secure.  There is a minimum password length requirement for AES as follows:

 

128 Bit - 8  Characters

192 Bit - 16 Characters

256 Bit - 32 Characters

 

Backup and Restore times might take slightly longer if AES encryption is used.

 

 

Disk Space Management

 

 

Disk space management allows you to automatically purge the destination directory of old backups to make space available for the latest.

 

If a Full backup is removed from the destination directory then all linked incremental and differential backups will also be removed as these are now invalid.

 

An Image will not be purged / deleted, regardless of age,  if you are running a incremental or differential backup and there is only one full image in the destination directory.

 

 

Auto Verify image

 

Choosing this option will automatically verify each image or backup file when it is created. This is generally only necessary when writing to optical media (CD/DVD) as this media is less reliable than other storage types.

 

 

If an image or backup file fails verification then this always indicated a hardware failure. This is most likely to be the storage medium, but can also be due to main memory (RAM) errors.
