ssnaps

Tool to simplify snapshot management and remote backup using libbtrfsutil.

Features

• None

Coming soon

• No ID abstraction, commands use the same IDs as btrfs itself.
• Fast(er) comparison mode just showing additions and deletions.
• Difference in pairs between n snapshots either by id or name.
• Fast space-usage estimates.
• Preservation of exclusive monthly, weekly, daily, and recent snapshots and / or backups.
• Remove snapshots when free space under an amount or over a percentage of use.
• Backups.
• Documentation.
• Configs.
• Systemd units.
• Rollback of any subvolume either via set/get default or by namechange.
• all-in-one application.
• btrfs-progs style interface (e.g. ssnaps [[[[[[[c]o]m]p]a]r]e] for ssnaps compare)
• Reduced set of snapshot types, no pre-post / number - ssnaps will only manage backups, timeline, and read-write snapshots.
• snapper conversion.
• man page
• help
• undochange that reflinks

Eventually?

• GUI for rollback, comparisons etc.
• gettext translations.
• zfs support.
• bcachefs support.

Setup

• Flat layout needed for rollback.
