**Motivations:** - Export Signet and mining wallet backups to git with only 2 versions kept - Document and add backup/restore scripts for signet and mining wallet **Correctifs:** - Backup-to-git uses SSH URL for passwordless cron; copy timestamped files only; prune to 2 versions; remove *-latest from backup repo **Evolutions:** - data/backup-to-git-cron.sh: daily export to git.4nkweb.com/4nk/backup - save-signet-datadir-backup.sh, restore-signet-from-backup.sh, export-mining-wallet.sh, import-mining-wallet.sh - features/backup-to-git-daily-cron.md, docs/MAINTENANCE.md backup section - .gitignore: data/backup-to-git.log **Pages affectées:** - .gitignore, data/backup-to-git-cron.sh, docs/MAINTENANCE.md, features/backup-to-git-daily-cron.md - save-signet-datadir-backup.sh, restore-signet-from-backup.sh, export-mining-wallet.sh, import-mining-wallet.sh - Plus autres fichiers modifiés ou non suivis déjà présents dans le working tree

# Create a full datadir backup (blocks + chainstate + config) from the running
|
|
# Bitcoin Signet container. Use this on the machine that has the chain you want
|
|
# to keep (e.g. height ~11535), then copy the archive and run restore-signet-from-backup.sh

# on the target machine.

# Usage: ./save-signet-datadir-backup.sh [output_dir]
