+# Script Name: AppBackup-restic.sh
+# Description:
+#   Creates a backup of a web application and optionally its MySQL database.
+#   The script archives the application home directory locally and backs it
+#   up to a Backblaze B2 repository using Restic.
+#
+# Usage:
+#   AppBackup-restic.sh --appname <name> --appuser <user> [--apppassword <password>]
+#
+# Author: Charlie Silverman
+# Version: 20261031-01
+#
+# Requirements:
+#   restic, jq, awk, tar, mysqldump (when --apppassword is used),
+#   mailx or mail (for email notifications), numfmt (optional, for
+#   human-readable sizes).
+#   Restic environment file: /root/.restic-env
+#
+# Versioning:
+#   Versions use the format YYYYMMDD-xx, where YYYYMMDD is the release date
+#   and xx is the release number for that day, starting at 01.
+#
+# Revision History:
+#   1.0         - Initial version.
+#   1.1         - Added logging to file.
+#   1.2         - Added strict error handling, input validation, and FQDN support.
+#   1.3         - Added trap-based error logging and improved operational visibility.
+#   1.4         - Added application-specific log files, interrupt handling,
+#                 and enhanced logging.
+#   1.5         - Added command-line help.
+#   1.6         - Replaced positional parameters with named command-line options
+#                 and added support for short/long option formats.
+#   1.7 (a)     - Added --no-tablespaces to mysqldump. Added --single-transaction
+#                 to eliminate the need to lock tables during backup.
+#   1.7 (b)     - Added email delivery of current execution log on success,
+#                 failure, or interruption.
+#   20261031-01 - Consolidated the two divergent 1.7 versions into a single
+#                 script. Adopted YYYYMMDD-xx versioning scheme. Version is now
+#                 defined once (SCRIPT_VERSION) and used in help and logs.
+#                 Removed SFTP upload; backups always go to Restic.
+#                 Restic snapshot details (ID, parent, tags, file/dir counts,
+#                 data added, snapshot size, duration) are now written to the
+#                 logs. restic backup now runs with --json and the details are
+#                 read from its backup summary. Added required-command check.
+#                 Temporary restic output is removed on failure or interrupt.

 # Version History:
 # 1.0.0 - Initial build
 # 1.1.0 - Added exception list via text file
+# 1.1.1 - Added snapshot size to log
+# 1.1.2 - Added aggregate backup size to end of log
+# 1.1.3 - Added GiB to total backup size information
+# 2.0.0 - Modified to save all files to a folder tree for backup rather than
+#         creating a single monolithic archive.  This will allow restic to
+#         properly manage snapshots
+# 2.0.1 - Changed exception lookup to case-insensitive
+# 2.1.0 - Added email delivery of current execution log. Added
+#         success/failure/interruption notifications and run-specific logs.
+# 2.1.1 - Added automatic cleanup of staging directories on backup failure
+#         or interruption.
+#         Added cleanup_staging() helper function.
+#         Added CURRENT_STAGING_DIR tracking.
+#         Added automatic RUN_LOG cleanup during failure and interruption.
+#         Improved housekeeping to prevent orphaned staging data after
+#         unexpected termination.
+# 2.1.2 - Added EMAIL_TO and EMAIL_FROM variables for reports.
+# 2.1.3 - Added DOCKERUSER variable for account to use for launching contaners
+# 2.1.4 - Restic snapshot details (ID, parent, file/dir counts, data added,
+#         total size, duration) are now written to the logs.
+#         restic backup now runs with --json; snapshot size is read from the
+#         backup summary instead of parsing 'restic snapshots' table output,
+#         so it always refers to this run's snapshot.
+#         Removed dependency on bc (awk used for arithmetic).
+#         Added total new data uploaded to end of log.

+#!/bin/bash
+#
+# Script Name: openwrtupload.sh
+# Description:
+#   Backs up OpenWrt configuration archives to a Backblaze B2 repository
+#   using Restic. Each .gz archive found in the source directory is
+#   extracted to a staging directory, backed up with Restic, and then
+#   removed along with the staging directory.
+#
+# Usage:
+#   openwrtupload.sh
+#
+# Author: Charlie Silverman
+# Version: 20261031-01
+#
+# Requirements:
+#   restic, jq, awk, tar, numfmt (optional, for human-readable sizes).
+#   Restic environment file: /root/.restic-env
+#
+# Versioning:
+#   Versions use the format YYYYMMDD-xx, where YYYYMMDD is the release date
+#   and xx is the release number for that day, starting at 01.
+#
+# Revision History:
+#   20261031-01 - Added script header and YYYYMMDD-xx versioning.
+#                 Added strict error handling with error/interrupt logging;
+#                 an archive is no longer deleted if its backup fails.
+#                 Staging directory is cleaned up on failure or interrupt.
+#                 Restic snapshot details (ID, parent, tags, file/dir counts,
+#                 data added, snapshot size, duration) are now written to the
+#                 log. restic backup now runs with --json and the details are
+#                 read from its backup summary. Added totals at end of run.
+#                 Added required-command check.
