Hi all
I was testing the ZeXtras backup suite with data exported (from a test copy) of our mail server through the Migration Tool to have a better idea on a real scenario in case of migration/recovery/etc
The original server is running with ubuntu 10.4 64 bit and Zimbra 7.1.4 OSE with 160 mailbox for 40 gb of data and the latest version downloaded two days ago of the migration tool plugin. The export went ok with no error message as showed on the report
This is an automated notification from ZxBackup about Export.
Operation Export Completed.

Once started the import the procedure the users was immediately created with their own preferences and the mail recovered from the backup starting from the admin acccounts

about unrestored items, how i can identify what is missing (and maybe why)
Also one more question on restoring a domain from scratch.... if i have to restore the domain CAT.com the right way is to create a CAT.com domain on a new machine and then recover all the data (excluding the special account like ham. spam and viruses) or is better create a temp domain like DOG.com restore CAT.com and then delete DOG ones?
Sorry if question sound dumb but i've not found on the wiki and i'm a new zimbra user in learning mode 🙂
Thanks

about unrestored items, how i can identify what is missing (and maybe why)
Also one more question on restoring a domain from scratch.... if i have to restore the domain CAT.com the right way is to create a CAT.com domain on a new machine and then recover all the data (excluding the special account like ham. spam and viruses) or is better create a temp domain like DOG.com restore CAT.com and then delete DOG ones?
Sorry if question sound dumb but i've not found on the wiki and i'm a new zimbra user in learning mode 
Thanks
