Backup and recovery
PM3 creates compressed backups of the TinyDB file before write operations.
Backups are stored in ~/.pm3/backups/.
If the database is corrupted at startup, PM3 prints a restore hint. Manual restore example:
gunzip -c ~/.pm3/backups/pm3_db_YYYYMMDD_HHMMSS.json.gz > ~/.pm3/pm3_db.json
Log rotation
Process log files are managed through RotatingFileHandler and can be configured with:
log_max_byteslog_backup_countlog_compress
When log_compress=true, rotated logs are gzip-compressed.
