Immutable Backup: qualcuno ha provato questa nuova funzionalità ?

Ciao anche se è passato un po’ di tempo, se può interessare segnalo questo modello dal nostro Configuratore Server (NT Nuove Tecnologie)

24 HDD Slot e connettività 10Gbit 

Sono i timeout prima degli ERROR  nel file di log che mi fanno propendere per un qualcosa assolutamente non dovuta all’immutabile ma all’host su cui si trova…. E ne è conferma che ora la vm che prima andava in errore ora si è completata. 

Hai aperto il case a VEEAM?

non è che il proxy sia necessario o meno per l’immutabile…. è per capire il tutto….a cosa corrisponde l’IP 192.168.2.3? A mio avviso comunque è il momento di aprire un case al supporto. 

@Link State 

su hyper-V non ho nessun proxy installato. E’ necessario per l’Immutable?? 

sui log ho trovato questi Error:

ma ho capito ben poco!!

@Andanet 

come proxy ho solo questi:

Si l’ambiente è su Hyper-V è non c’è nessun cluster 

@Link State 

l’errore completo dice:

Error: read: Connessione in corso interrotta forzatamente dall'host remoto --tr:Cannot read data from the socket. Requested data size: [4]. --tr:Client failed to process the command. Command: [connectByIPs]. --tr:event:1: --tr:event:6: --tr:event:3:

sull’event viewer su Sistema e Sicurezza non ho nessun errore!

@Andanet 

Ciao Antonio,

ti mando lo screen del backup, come ti accennavo precedentemente solamente la FILE1 non completa il task riportando come errore “Connessione in corso …..”

e non riesco a capire la motivazione. Il backup giornaliero viene tranquillamente effettuato è sull’immutable che lo riscontro! Grazie

Ciao, usiamo Veeam Hardened Backup Repository fin da quando è stato rilasciato e ci troviamo molto bene.

Normalmente proponiamo storage server dedicati su base Supermicro, questo ci consente di realizzare soluzioni con capienze e performances molto elevate, interconnessioni a 10Gbita costi contenuti.

Usiamo SO Linux Ubuntu 22.04 LTS e tra i benefici di creare backup repository Linux su filesystem XFS ho particolarmente apprezzato il risparmio di spazio grazie alla tecnologie "space-less" per i synthetic full backups.

Buongiorno, 

ho seguito la seguente guida (https://nolabnoparty.com/veeam-v11-hardened-repository-immutability-installazione-pt-1/) utilizzando una Ubuntu 20.04LTS e completando tutti i task, ma durante il job ottengo questo errore:

Processing DC1 Error: write: Connessione in corso interrotta forzatamente dall'host remoto
--tr:Cannot write data to the socket. Data size: [16].
--tr:Client failed to process the command. Command: [connectByIPs].

--tr:Failed to connect to target endpoint.
--tr:Client failed to process the command. Command: [connectByIPs].
--tr:event:1:
--tr:event:3:

mentre altre VM vengono completate  correttamente:

17:39:49    Network traffic verification detected no corrupted blocks     
17:39:49    Processing finished at 24/02/2023 17:39:49     
 

non riesco a capire dove sta il problema, qualcuno ha avuto lo stesso errore?

Grazie
  

Buongiorno Marco, confermo: è una scelta tecnica obbligata, almeno per il momento. La funzionalità di immutabilità per i backup Veeam è infatti realizzata sfruttando uno degli attributi nativi in Linux, il flag +i (impostabile tramite comando chattr)

Per maggiori informazioni: 

• https://helpcenter.veeam.com/docs/backup/vsphere/hardened_repository.html?ver=110
• https://linuxhint.com/chattr-command-linux/

Aggiungo, agli ottimi spunti degli utenti e dei colleghi, uno dei tanti progetti del collega Timothy Dewin (l’autore del Restore Point Simulator che tutti noi amiamo e usiamo praticamente ogni giorno  ): si tratta di uno script che automatizza e semplifica la creazione di un Linux Hardened Repository.

Ciao Fabio,

oltre alle risposte iper-esaustive di Raffaele, ti segnalo questo whitepaper che personalmente ho trovato molto utile:

https://www.veeam.com/wp-guide-protect-ransomware-immutable-backups.html?wpty

Ciao

Anzi scusate… approfitto… immagino sia possibile usare l’Immutable storage repository anche per eseguire un secondo processo di backup copy, oppure è disponibile solo per il processo primario di backup ?
