great tip alpha! you can also look in your programs settings and some dawś have the ability to auto save every 5, 10, 15 minutes etc....
i have a few tips to add, these are mostly to save time.
1. in most daws i have used you can set up a template to get your project started quickly. for expample, i all ways record with drums, bass, guitar, so i can set up a template with 8 tracks of drums . i like all my drums routed to a drum bus except the kick. i usually have an eq on each seperate drums track. i then set up a mono bass track with a compressor and i route that compressor to side chain from the kick drum to duck that sound. i usually then will have 2 mono tracks panned right and left for my first guitar part. i will need 4 or 5 midi tracks to start of with that will eventually route to drums or possibly a synth/organ. this is just how a session will allways start for me... but usually not end... now if i set that up and save that as a template... i can cut out all that work very quickly by just loading that template to start each project.
realize this may help you on A LOT of your songs... but some songs you want to start with a different approach... possibly a completely different configuration.. so dont let a template ¨trap¨ you into making the same songs over and over.... but in general those 3 elements are in all my songs so having that template ready can get me started quickly.
2. if your planning to record live. before you even turn on the computer it would be a good idea to get your signal chain ready... having the mics and preś and hardware set up and tuned in the best you possibly can will prevent you from trying to ¨correct¨ sounds in the box that you could achieve without the aid of software. this will give you better results in the final recording.
3. if you record live.. anything... record dry. do not put any effects on it... even if you have a 2000 dollar hardware box or a bad ass distortion pedal... learning to record dry and then re-amp or add effects later is the best idea. even if this requires some complicated bussing... if you record a track with reverb on it and later decide you want a different verb or none at all.. your stuck.. you will have to retrack. working as non destructive as possible is the goal that way you can all ways go back a few steps and start again.
4. i know cash can be an issue.. but never skimp on cabling... every part of your signal chain is important... from the most expensive device to the audio interface.. but also.. EVERY THING in between.. a slight buzz or hum from a cable will wreck a performance quickly...
