continuous-integration/drone/push Build is passing
files/temp is TDLib's own redundant download cache — the worker already prunes it after every ingestion run (see the recent optimizeTdlibStorage fix), and its content still lives in the source/destination Telegram chats regardless. With the cache grown back to ~59GB between prune cycles, tarring it made today's backup run for 4+ hours straight, fighting the actively-ingesting worker for disk I/O and degrading the whole host. Excluding it keeps the backup to what's actually irreplaceable: the DB dump and the TDLib session state itself.
