FSA Temp Size question

Hi,

I'm using Enterprise Vault 10.0.3 (only FSA) and just want to get some answer about max size of temp folder. I'm going to archive files greater than 500 GB. What should be the size of TEMP volume to succefully archive these files ?

I've read the "Enterprise Vault Best Practice Guide" and it says - about Windows Temp Folder expected size 2 GB. However when large files are going to archive temp volume going to grow and grow until end of free space and File System Archiving Task stop processing with error: There is not enough space on the disk.  (0x80070070).

Regards,
