Memory consumption with many files or repo size

Support
1

v0.13.0
Everything works perfect with 16Gb ram (10-15 tasks for ~50Tb total), before i backup few new folders for ~100Tb more and probably 50-100+ millions files inside.

Docker container repeatedly fall with memory leak, about every 1 min. Can’t get kopia blob stats kopia content stats because it fall faster).

With 100Gb ram it consume ~45-50Gb then stop, and after maintenance free up all memory. Without running tasks kopia consume 2-4Gb. Still waiting kopia blob stats, it takes very long time.

What should i increase and which ratio recommended? like for ex 10Gb memory for each 100Tb.

I saw recomendations split backups to different repo. But at web i can connect only 1 repo at once. How work with that? Edit repository.config manualy?
found solution 1docker=1repo, but that reeaaally not very good idea. Multiple Repositories (using Docker)? - #2 by tugdualenligne
