30 LG External HDD Manual
Nero BackItUp has five sync types:
1. Mirror
The Mirror type synchronizes two folders.
New and updated files are copied from one folder to the other folder. Files that are deleted in
one folder are also deleted in the other folder.
2. Copy
The Copy type copies new and updated files from the left to the right folder.
Files that are deleted in the left folder are also deleted in the right folder.
3. Partial synchronization
The Partial synchronization type copies updated files from the right to the left folder.
This sync type only deals with the same files, new files or deleted files will be ignored.
4. Update
The Update type has the same function as the Copy type with the exception that the Update
type does not delete.
5. Partial mirror
The Partial mirror type has the same function as the Mirror type with the exception that the Par
tial mirror type does not delete.
Note - Nero BackItUp cannot identify changed or renamed files during the first run.
The reason is that sync information is stored in a separate file and changes are
compared to this information.
