# Bitcoin wallet-file backups: what a seed may not preserve A wallet-file backup preserves the data included in that wallet database; a mnemonic restores keys through its defined derivation process. These are not always equivalent. Imported keys, wallet policies and local records can need separate preservation. Use the wallet’s supported backup operation and keep the format, encryption credentials and software compatibility needed for restoration.

Core’s sendtoaddress documentation explicitly says its comment fields remain in the wallet rather than the transaction. A key-only recovery can therefore locate funds without reproducing every note, contact label or accounting context. Conversely, a file containing a transaction history does not automatically contain usable spending authority.

Restoring only the seed need not recover the imported-key portion. The visible total of 100,000 does not establish a single recovery source. Electrum documents this distinction explicitly for imported-key wallets. The exact contents of a backup file depend on the product, so preserve its documented recovery material rather than assuming every file named wallet has the same scope.

Record which product and format created it. Encryption can make a backup unreadable without its required password. A software upgrade can change wallet-file format. Electrum warns that an older version may not read a file opened by a newer one. A backup is valuable only when the necessary data and a compatible recovery procedure remain available.

Only information actually published in transactions is on the chain. Core wallet comments, for example, are local data. Recovering key-derived transaction history does not automatically restore those local annotations. Evidence: [sendtoaddress RPC](https://bitcoincore.org/en/doc/29.0.0/rpc/wallet/sendtoaddress/) ### Is copying a seed enough for a wallet with imported private keys? Not necessarily. A seed regenerates its derived hierarchy; unrelated imported keys can require a separate backup. Identify the wallet’s actual key sources and supported export or backup method.
