These software have option to config directory using .ignore file

1. Kopia - .kopiaignore
2. Restic (hard to use)

• --exclude-file
• Ignore File: create a custom text file e.g., excludes.txt
• .exclude_me supports --exclude-if-present, which lets you skip any directory containing a specific file, such as .exclude_me.
• Uses gitignore-style syntax
• wrapper like Restatic - crawls directories before Restic starts and looks for .restaticignore files. It merges all those local files into one big exclude list and passes it to Restic automatically.

3. Duplicacy .duplicacy

• ~While the official binary uses .duplicacy/filters, many users use scripts to generate that filter file by scanning for .cvsignore or custom ignore files in subdirectories.~, * _{https://forum.duplicacy.com/t/filters-include-exclude-patterns/1089/23}, * _{https://github.com/TheBestPessimist/duplicacy-utils}, * _{https://github.com/markfeit/duplicacy-scripts}, * _{https://github.com/gilbertchen/duplicacy/issues/337}, * _{https://forum.duplicacy.com/tag/filters}

Rclone (Only ignores no option to config)

1. --exclude-if-present .rcloneignore (any name)
2. Global --exclude-from list.txt

Why is it only recommended for “Large-scale cloud copies” and “Google Drive/Dropbox/S3”?

Borg (Only ignores no option to config) .borgignore

FreeFileSync (Maybe global only).ffs_gui or .ffs_batch

How to set up like this with features -

1. Forever full backups/DeDuplication - Option Delete changes older than x. Where full-backup is taken once then incremental-s are merged. I have heard terms like, snapshot and CBT but don’t understand it.
2. Save a “Ghost” for excluded data ie only Filename, Metadata and Folder-Structure.
3. “File Change Tracker” to see summary of what files are moved/deleted/renamed between 2 backups. Like Kopia’s https://kopia.io/docs/reference/command-line/common/diff/
4. “File History” where I see previous version of files on the main disk. Like Kopia’s kopia snapshot list <filename>

To Backup

• External and Internal Disk (files) to backup,
• all separately backup-ed to the same backup disk, .
