Failed to scan files: Out of memory
You may get this out of memory error when working with any of the consumer-level Cloud services as listed below:
- Amazon Cloud Drive
- Office 365 (OneDrive for Business and SharePoint)
- OneDrive (Personal)
- Google Drive
The simple solution is to switch to the 64-bit version of SyncBackPro (available for V8 and newer). This lets SyncBack use all available memory instead of being restricted to just 2GB (as is the case with the 32-bit version).
There is a special type of cloud data which needs to be stored in memory. This data include pointers, special-ID, para-ID, etc. which are inter-linked together which relates to how the Cloud service handles and processes cloud-based data files.
Due to the way these cloud file details interrelate with one another, SyncBackPro has to store them in memory until the entire batch of files in-scope have completed processing and it can't simply transfer them over to disk storage to free up memory.
As a result, if there are a large number of files to be processed, SyncBackPro will run out of memory eventually. If you are using the 32-bit version of SyncBackPro then it can only use 2GB of free memory in the PC system, regardless of how much RAM is available.
If you encounter such errors during a profile run, we recommend splitting up your data into several profiles and then place them in a Group so that each profile is processed sequentially. Source path and file selections on each separate profile may need to be tweaked, with each profile pointing to a sub-set so that the data can be backed up in batches.
Alternatively, if you are using SyncBackPro V8 then consider switching to the 64-bit version, which can use all available free memory.
