Dear Customer,
The system was being reinstalled, so all logs and information are being erased.
However you have mentioned that all data on server is corrupted at same time, hence I consult with developer for further advice about possibility if you may be infected with synolocker and other malware.
As the entire system were reinstalled, so there is no trace on log. But we checked your data's modify time, all being modified on 3rd Aug same time (encrypted by synolocker at same time).
If you use File Station to check most of the corrupted data, then their modify time are all in 3rd Aug, which is around the time synolocker issue start to appear and your symptoms matches it.
According to the information you provided, It seems your DiskStation has been infected by the recent ransomware called “SynoLocker.”
Affected users may encounter one of the following symptoms:
When attempting to log in to DSM, a screen appears informing users that their data has been encrypted and a fee is required to unlock data.
Abnormally high CPU usage or a running process called “synosync” (which can be checked at Main Menu > Resource Monitor).
DSM 4.3-3810 or earlier; DSM 4.2-3236 or earlier; DSM 4.1-2851 or earlier; DSM 4.0-2257 or earlier is installed, but the system says no updates are available at Control Panel > DSM Update.
Unfortunately, Synology are unable to decrypt files that have already been encrypted.
If you happen to possess a backup copy of your files (or there are no critical files stored on your DiskStation), we recommend following the below steps to reset your DiskStation and re-install DSM. * Migration may still leave these "synolocker" in your system.* However, resetting the DiskStation removes the information required for decryption, so encrypted files cannot be decrypted afterward.
Follow the steps in this tutorial to reset your DiskStation:

DSM 4.3-3827 or later
DSM 4.2-3243 or later
DSM 4.0-2259 or later
DSM 3.x or earlier is not affected
