For the discount rate, if you order multiple licenses at one time, the volume discount rate will be applied automatically. And we are discuss with our e-commerce provider iportis.com to implement a new discount system that can give larger discount.
The compress and encrypting feature is tough-binded, if you use the compress feature, the encrypting feature is also used. May be we would add a new option to compress the file only.
For the deleting and moving issue, I would like to clear the following points’
1. BestSync detects file deleting and moving from the second time of synchronization.
Because when the task runs at the first time, it can not know if the files that exist in only one side are new added in the folder or deleted from the other folder.
2. If there are two many files (you said 100GB) in the folder, it may take days to synchronize files to the FTP server. If you reboot the system before BestSync complete the synchronization, BestSync can not save the synchronization result to DB, and if your FTP does not support modifying the timestamp of file. After the PC is rebooted, BestSync has not the DB of the last time, and can not calculate the timestamp of the files in FTP server, this causes all the files be re-synchronized after reboot.
To avoid this problem, please let BestSync complete the synchronization before reboot. Or use an FTP server that supports modifying timestamp of file.
We have released the new version 5.4.15, the new version has added a new feature to detect file moving.
