My microSD card suddenly failed while it contained about 18,000 FLAC songs collected over more than a decade. My music player stopped finding the files, and my computer no longer recognizes the card. I may be able to rebuild much of the library from Bandcamp purchases, old transfers, and other sources, but recovering, renaming, and organizing everything will take a long time.
My laptop does not have enough internal storage to hold the entire collection, which is why I never created a complete backup. Once I rebuild the library, what would be the most practical and affordable way to protect it without relying on computer storage? I would also appreciate advice on storage types, backup routines, and anything else I should know to avoid losing everything again.

You do not need a computer with enough internal space for the whole collection. A large external HDD is usually the most cost-effective option for FLAC files, while an external SSD is faster and more resistant to physical shocks but generally costs more. Use a second drive for a separate copy, then run a scheduled file-sync or backup job instead of copying everything manually each time.
The important part is having multiple independent copies rather than searching for one perfect storage device. Memory cards, hard drives, SSDs, and cloud accounts can all fail or become inaccessible. Once you recover the music, organize it on an external drive, duplicate it to another drive, verify that the files open correctly, and keep at least one copy outside your home if the collection matters to you.
The usual recommendation is the 3-2-1 backup rule: keep at least three copies, on two different types of storage, with one copy stored somewhere else. For example, you could keep the main library on a large external hard drive, a second copy on another drive or a local NAS, and an additional copy with a reputable cloud-storage provider. That protects you if a drive fails, your computer is damaged, or something happens to your home.
For especially important files, it can also help to rotate drives periodically and keep one physical copy at another location. Cloud storage and optical discs can be useful extra layers, but they should not be your only backup.

That makes sense. I had focused on finding enough space for one complete copy, when the real solution is setting up a routine with several copies.
