I used BE.15 on Windows 2012R2.
I want a solutions for delete or cleanup a PDVFS .LOG in C:\Program Files\Symantec\Backup Exec\Logs\PDVFS\
Because it's too big folder (about 70 GB.). And drive C: almost full.
first of all, ensure that the debugging for deduplication is disabled (https://www.veritas.com/support/en_US/article.TECH136441). Then, to remove already created logs, stop Backup Exec services, delete the files, and restart services.
