# Timebank Backup Retention Policy Configuration
|
|
#
|
|
# This file controls how long different types of backups are kept before being automatically cleaned up.
|
|
#
|
|
# IMPORTANT NOTES:
|
|
# - Values are in days unless otherwise specified
|
|
# - Changes take effect immediately on next cleanup run
|
|
# - Lower values = less storage used, shorter recovery window
|
|
# - Higher values = more storage used, longer recovery window
|
|
# - Test changes with --dry-run before applying
|
