 * This is a continuation of [https://teamupdraft.com/forums/ticket/repeated-migration-failures/#post-7545677](https://teamupdraft.com/forums/ticket/repeated-migration-failures/#post-7545677)
   which was closed out prematurely.
   Essentially, I was using the SendTo feature
   to migrate sites. The backup to the new sites reported success. Repeatedly, the
   restoration on the new site failed due to a defective archive.Updraft support
   says:
 * > Just to clarify, the backup archive is checked for completeness/integrity when
   > the restoration process attempts to unpack and restore it. This is why the 
   > transfer itself may complete, but an issue with an archive may only become

   > An incomplete or corrupted archive can occur for several reasons, including
   > interruptions during backup creation or transfer, server resource limitations,
   > storage/filesystem issues, or network-related interruptions.
   > I understand your concern that the transfer was reported as successful despite

 * I fully understand that archives can be corrupted; that’s why it’s important 
   to verify them. I can’t understand why hashes aren’t computed and compared. This
   seems like downright malfeasance if not incompetence.
   If this happens on site
   migration, why would it be any different with backups to Updraft Vault, S3, etc.?
   At this time, I don’t have confidence in Updraft. I’m afraid that it’s back to
   cron jobs to backup the database and rsync everything to a remote server.Also
   as an aside, I find it unseemly to close out a thread without truly resolving
   it. Sounds like a cover-up.

 * Hi,
 * We cannot offer support for the premium plugin here. It’s against the WP forum
   rules. I have opened the thread back up for you in our premium support forum
 * The premium forum is only really intended to assist people who have lost access
   to their account. The best place for support is our helpdesk: [https://teamupdraft.com/support/premium-support-form/](https://teamupdraft.com/support/premium-support-form/)
 * You can check the integrity of file by downloading it and unzipping it. There
   is no cover up.
 * If you post your php error logs we can look into it forum (please do this via
   the premium support forum or the helpdesk.

 * Just to close out here before moving back to paid support, are you are saying
   that Updraft does not guarantee integrity of the backup and that users must download
   and inspect each file to assess integrity of the backup. Should we do this each
   day?

 * No, I am not saying you should download and inspect them every day.
 * I am saying that if you do have a file you are concerned about you can download
   and unzip as a really quick check.
 * We can’t 100% guarantee anything and we would not claim to. The backup depends
   on much more than just UpdraftPlus such as your hosting environment, your server,
   your remote storage and your resources. This why we always recommend you have
   at least two backups at all times (ideally more in case you get hacked and you
   need to go back further)
