How To: Synchronize Data

Using Robocopy

Batch File: Mirror a directory (synchronize). Output Robocopy log appending date and time stamp
save as Rename.bat and replace “Rename” with Backup job name of preference…

Mirror Desktop
robocopy.exe “%userprofile%\desktop\Rename” “Z:\Backup\UserProfile\desktop\Rename2″ /MIR /SEC /XA:SH /XJD /XF *.PST /R:3 /LOG:”Z:\Backup\UserProfile\Logs\Rename-%date:/=-%-%time::=-%.txt”

Mirror User Profile
robocopy.exe %userprofile% “Z:\Backup\UserProfile\Profile” /MIR /SEC /XA:SH /XJD /XF *.PST /R:3 /LOG:”Z:\Backup\UserProfile\Logs\Rename-%date:/=-%-%time::=-%.txt”

When using the /PURGE or /MIR Commands with Robocopy beware that if the destination has files that the source does not, it will delete! When using the /MIR or /PURGE commands make sure that you are specifying exact UNC locations such as “\\hostname\parent\subdir” and that you want that directory mirrored with the source. Common mistakes may include trying to copy source to the root of the destination in which anything in the root destination gets deleted because the files/folders do not exist in source.

I’ve had great success with synchronization using PureSync by Jumping Bytes. Jumping Bytes offers with it’s free personal version the following benefits:
1. Synchronize
2. Backup
3. Restore
4. Subfolders/multiple folders
5. automatic synchronisation/backup
6. Filter (size, date, …)
7. Paths with environment variable, e.g. %USERPROFILE%
8. Paths with wildcards e.g. for date and time
9. Photo-Sync

Allway Sync
I’ve also had great success with with Allway Sync, however, you should pay for a Pro license if you use this software for a commercial purpose or to synchronize more than 40,000 files in 30-day period.
