/home/node and /home/linuxbrew) is backed up nightly into seven rotating slots, so the last seven nights are available as restore points. You can also take a backup on demand, into a separate slot that only your next on-demand backup replaces. A new instance has none until its first nightly pass, so take one on demand if you need a restore point before then. Backups and restores are free.
