When it comes to backing up your hard disk I often hear of Emergency Boot diskettes, CD-ROMs, ZiP/Jazz disks but there's one thing I never hear mentioned...
Next time you're in the Early Startup Menu have a look for CC0: - a nice 2MB PCMCIA SRAM card would boot silently, instantly and would hold far more data for recovery purposes than an 880k floppy. You could put DiskSalv, SFS-salv, DOpus, AmiCDFS, RDB-Salv and whatever else on it.
Remember that CC0: has boot priority 3 - higher than floppy and hard disk and of course, unlike ZiP or CD-ROM the driver is permanently in ROM (which is thankfully write protected!).
