Create Synchronicity: Complete Backup And Synchronization
Create Synchronicity (Version: 5.2.1 tested for this review) is a very capable backup tool, it can synchronize and mirror folder structures. Creating a profile comes first along with choosing source and destination folders. The type of backup or synchronization can then be chosen and file types included or excluded, with regex support, if necessary. ‘Propagate Updates’ will differentiate between files updated and only those added or deleted. The Strict file time comparison check forces Create Synchronicity to check modified dates to the second so as to not miss often updated files.
Right clicking on the profile name brings up options to edit settings, preview the synchronization, do the actual synchronization and also enable scheduling.
There are three synchronization modes or types available, quoting from the developer site they are:
Left to right (Mirror): New and modified files are copied from left to right. Deletions that occurred on the left are replicated (“mirrored”) on the right. In this case, the right folder becomes an exact copy of the left one, except that files updated on the right side are not reverted to their original state (Unless “strict mirror” is selected.).
Left to right (Incremental): New and modified files are copied from left to right, but deletions are not. In this case, the right folder somehow keeps an incremental history of changes that occurred on the left.
Two ways (Incremental): New and modified files are copied from left to right, and from right to left. No deletions occur. This is especially useful if changes occur also in the destination (eg. your documents on a USB stick)
Create Synchronicity has an expert mode (enabled by adding Expert mode:True to mainconfig.ini or pressing Ctrl+Alt+E) that, among others, enables new variables and md5 integrity check on copied files.
Create Synchronicity includes some command line support. It can also sync to network drives either by the user mapping network drives or using UNC (Uniform Naming Convention) paths.
There are also some hidden settings available to for example create compressed (gzip or bzip2) backups.
Every command line and every setting is fully explained on the detailed Help page. Create Synchronicity is open source, available in both portable and installer downloads. It requires Windows 2000 or newer and the .Net Framework 2.0.
