+## Memory Issues
+
+Corso's memory usage depends on the size of the resource being backed up. The maximum memory usage occurs during full
+backups (usually the first backup) vs. later incremental backups. If you believe Corso is using unexpected amounts of
+memory, please run Corso with the following options:
+
+- Prefix the Corso run with `GODEBUG=gctrace=1` to get GC (Garbage Collection) logs
+- Add `--log-level debug --hide-progress --mask-sensitive-data`
+- Redirect output to a new log file (for example, `corso-gc.log`)

+information on the size of the Exchange mailbox, OneDrive location, or SharePoint site that you are having an issue
