How to Back Up and Preserve Your Digital Game Collection

Quick answer

Back up digital games by copying install folders, save files, and account entitlements to two separate drives, then verify one restore. For physical releases, keep the cartridge or disc, box, and manual together because those items are your most durable backup. Start with the games you cannot re-download, then schedule a monthly refresh.

Digital storefronts can remove a game, a patch can break a save, and a drive can fail without warning. If you want to preserve a digital game collection, you need copies you control, not just licenses you can access. The good news is that a workable backup routine takes an afternoon to set up and minutes to maintain.

This guide walks through an ordered process for PC, console, and retro libraries. It also explains when a physical edition is the stronger preservation choice, using real examples from Premium Edition Games stock such as Crater Song - Original NES Edition and CARL - Deluxe Edition.

Start with an inventory of what you own

Before you copy anything, list every game you want to preserve. Include the platform, where you bought it, whether you can re-download it, and whether it has online-only components. This list becomes your checklist, so you do not waste time backing up games you can always reinstall from a store.

Sort the list into three groups: games you cannot re-download, games with important local saves, and games you only play occasionally. The first group gets backed up first. The second group needs save-file copies even if the install files are replaceable. The third group can wait until your routine is running smoothly.

• Common mistake: assuming a store purchase is permanent. Licenses can be delisted, so treat re-download access as a convenience, not a guarantee.
• Checkpoint: you should be able to name the five games you would be most upset to lose.

Choose your backup drives and formats

Use at least two destinations: one external SSD or hard drive for fast access, and one second copy on a different drive or in cloud storage. Do not rely on a single drive, even a large one, because one failure takes everything with it. Label each drive with the date you last updated it.

For install folders, keep the original file structure so the game can find its assets. For save files, copy the entire save folder rather than individual files, because many games store progress across multiple files. If a game supports cloud saves, enable them, but still keep a local copy.

• Common mistake: backing up only the executable. Games often need asset folders, configuration files, and save directories to run after a restore.
• Checkpoint: test that your backup drive is readable on a second computer before you trust it.

Back up PC game installs and saves

For PC games, locate the install directory and copy the whole folder to your backup drive. Then find the save location, which is often in Documents, AppData, or the game's own folder. Copy saves separately so you can restore progress even if you reinstall the game later.

If you use a launcher, note your account name and any offline mode requirements. Some games need a one-time online check, so keep that detail with your backup notes. For games with mods, back up the mod folder and a list of mod versions, because a missing mod can make a save unreadable.

• Common mistake: copying saves while the game is running. Close the game first so files are not locked or half-written.
• Checkpoint: restore one save into a fresh install and confirm your progress loads.

Back up console games and account entitlements

On modern consoles, you usually cannot copy the full game, but you can back up saves and capture your purchase history. Export saves to a USB drive if the console supports it, and enable cloud saves where available. Then record your account email, purchase list, and any download codes in a document stored with your backups.

For cartridge-based systems like Nintendo Switch, the cartridge itself is a physical backup. Keep the case and insert, because those items carry the title and region information you need if you ever rebuild a library. If a game is only available digitally, treat your account access as the fragile part and document it carefully.

• Common mistake: deleting a game to free space without checking whether the save is stored locally or only in the cloud.
• Checkpoint: confirm you can sign in to your account and see your owned games list.

Preserve retro and physical releases properly

Retro cartridges and discs are already offline copies, but they still degrade. Store them away from heat, humidity, and direct sunlight, and keep boxes and manuals with the game. For NES titles, a clean cartridge and a working console are part of the preservation chain, so test each game periodically rather than assuming it will always boot.

Physical editions often include extras that digital versions never ship with, such as soundtracks, art books, and challenge cards. Those extras are part of the collection's story and can be the only surviving copy of a specific packaging design. Keep them together and note any disc rot or label damage early.

• Common mistake: storing cartridges loose in a bin where labels get scratched and boxes get crushed.
• Checkpoint: every physical game should have a known working console or adapter to play it on.

Verify, document, and refresh your backups

A backup you have never restored is a guess. Once a year, pick one game and restore it from your backup drive to a clean folder or spare console. If it launches and your save loads, your process works. If it fails, fix the gap before you need it.

Keep a simple text file with your backup dates, drive labels, and any account notes. Set a monthly reminder to copy new saves and purchases. Game preservation is less about one heroic effort and more about a repeatable habit that survives busy months.

• Common mistake: letting backups drift for years because everything still works today.
• Checkpoint: write the next verification date on your calendar before you finish.

Your backup routine in seven steps

1. Inventory your library: List every game, platform, purchase source, and whether it can be re-downloaded. Checkpoint: mark the games you cannot re-download and back those up first.
2. Prepare two backup drives: Use one fast external drive and one second copy on a different drive or cloud service. Checkpoint: label both drives with the date of your last update.
3. Copy install folders and saves: Copy the full game folder and the save folder separately, keeping the original structure. Checkpoint: close the game before copying so files are not locked.
4. Capture account and entitlement details: Record account emails, purchase lists, download codes, and any offline mode requirements in a text file. Checkpoint: confirm you can sign in and see your owned games.
5. Store physical games correctly: Keep cartridges, discs, boxes, and manuals together, away from heat, humidity, and sunlight. Checkpoint: test one retro game on a working console each year.
6. Verify one restore: Restore a single game and save from your backup to prove the process works. Checkpoint: if the restore fails, fix the gap before backing up more.
7. Refresh monthly: Copy new saves and purchases on a monthly reminder and update your backup notes. Checkpoint: schedule the next full verification for the same month next year.

Physical editions that double as backups

• Crater Song - Original NES Edition: A single-player co-op puzzle game in a sci-fi fantasy world, released as an original NES cartridge with a color label and full color manual. A working cartridge and manual are an offline copy you can play without a store account, which makes this a strong preservation pick for retro collectors.
• CARL - Deluxe Edition (PRE-ORDER): Deluxe Editions include a Nintendo Switch physical case and game with a double-sided insert, full color manual, challenge card, SNES-style box, Steelbook, and CD soundtrack. The soundtrack and printed extras are not part of a digital download, so the physical edition preserves material a digital backup cannot capture.

Backing up digital games is a habit, not a one-time project. Start with the titles you cannot re-download, keep two copies, and verify a restore once a year. When a physical edition exists, it remains the most reliable backup you can put on a shelf.
