Channel Merging Function

[Stoxis]

Currently, the Discord backup module provides the option to retain existing channels instead of deleting them before loading messages into them using the clearGuildBeforeRestore setting. However, this setting does not address the issue of merging backed up messages with pre-existing channels of the same name.

This feature request aims to enhance the backup bot by implementing a new functionality that intelligently merges backed up messages with pre-existing channels of the same name, ensuring a seamless restoration process without creating duplicate channels.

Proposed Changes:

• Modify the bot's behavior to retain existing channels without deleting them.
• Introduce logic to merge backed up messages with pre-existing channels seamlessly.
• Ensure that new channels are only created if a channel of the same name doesn't already exist.

Benefits:

• Preserves server organization and structure.
• Reduces clutter and confusion in the server during backup restoration.
• Enhances usability and flexibility of the backup bot.
