Recupero dati da file cancellati accidentalmente o unità bloccate in Ubuntu

Versione 1.0
Autore:Srijan Kishore

Questo tutorial ti aiuterà a recuperare i dati dai dati eliminati accidentalmente dai file system Linux. Questo è un errore molto drastico da parte di qualsiasi utente/amministratore che costa enormi sanzioni. Questo script sarà un vantaggio per i principianti/esperti nella gestione dei dati. Userò TestDisk per il recupero dei dati. Qui ho semplificato il compito con l'aiuto di uno script.

1. Sfondo

TestDisk è un potente software gratuito di recupero dati. Supponiamo di avere un'unità ext3/ext4 che si è arrestata in modo anomalo/cancellato con rm -rf o shift+delete come i comandi, con l'aiuto di TestDisk puoi recuperare i dati/file.
TestDisk può essere usato per

Correggi la tabella delle partizioni
Ripristina file da partizioni FAT, exFAT, NTFS e ext2/ext3/ext4

Oltre a queste funzioni, TesdDisk ha diverse funzionalità per la manutenzione/gestione dei dati

2. Requisito

Sto usando Ubuntu12.04 LTS su cui installerò TestDisk e implementerò lo script di recupero dati su un'unità bloccata. Questo script funziona bene con il sistema operativo Ubuntu. Anche se accade che uno qualsiasi dei dischi rigidi venga eliminato, basta collegare il disco rigido con la macchina Ubuntu ed eseguire lo script per recuperare i dati.

4. Esecuzione dello script

Copia semplicemente lo script sopra e incollalo nel file vale a dire. script.sh e dai i permessi di esecuzione allo script.

chmod +x script.sh

Nota:eseguire lo script con root utilizzando il comando

sudo -i #### Inserisci la password di accesso del sistema###########

Esegui lo script e ti guiderà ulteriormente.

sh script.sh

5. Finalizzazione

In primo luogo, lo script confermerà che l'utente che esegue lo script è root, quindi verificherà l'installazione dello strumento TestDisk. Ti reindirizzerà alla pagina di selezione dell'unità per il recupero dei dati.
