How One-way Synchronization Works
One-way synchronization is much simpler than multi-way
synchronization, but qFileSync supports two different kinds of
one-way sync: Mirror to, and Merge into.
To set up a one-way sync, add the folders (two or more) to be
synchronized to the Folders to Synchronize list
on the main dialog. Choose which folder is the data source (the
location from which files are copied) and make sure its Type
is set to Source folder. Then, set the other
folder(s) to Mirror to or Merge into.
The effects of each choice are as follows:
- When you use Mirror to mode, qFileSync
makes sure that the contents of the location you mirror
to are the same as the contents of the source folder. It
does this by
- Deleting any files in the mirror that are not
present in the source
- Copying any files from the source that differ
from the mirror. It doesn't matter if the copy at
the mirror has a newer date; qFileSync will still
copy over it with an older file from the source.
- When you use Merge into mode, qFileSync
copies newer files from the source location to the merge
location. qFileSync does not delete files from the
destination merge location, nor does it overwrite newer
versions of files at the destination. Merge into
is equivalent to Backup in qFileSync
v2.0.
Conflicts never arise when performing a one-way
synchronization because qFileSync is never unsure what to do.
