|

# Exports a container's appdata directory to a compressed tar archive.
|
||
# Stops the container before archiving and restarts it after — ensures clean consistent backup.
|
||
#
|
||
# Usage:
|
||
# container_data_export.sh ContainerName /path/to/appdata /path/to/output/dir
|
||
# container_data_export.sh Emby /mnt/media-servers/Media_Server/Emby /mnt/user/Backups/
|
||
#
|
||
# Output file naming:
|
||
# ContainerName_YYYY-MM-DD_HH-MM.tar.gz
|
||
#
|
||
# Use before major container updates, pool migrations, or when archiving
|
||
# a container you are removing from the stack.
|
||
#
|
||
# Supports --dry-run to show what would be archived without making changes.
