SymptomsBackup restoration is too slow, taking a very long time. In particular, IMAP Mail content restoration is the most time-consuming sub-task.
This issue occurs during migrations as well.
Solution for Plesk 11.xThis issue has been fixed in Plesk 11 MU#37. You should update your Plesk to this version of microupdate at least and set the SmartRestore parameter value to false in file "%plesk_bin%\BackupUtils\PSAMailRestore.exe.config"
Workaround for Plesk 9.x and 10.xYou may switch the restoration utility to using a native provider.
Warning: Before Plesk 11.0.9 MU#37 a native mail provider will restore the mail content, but the following messages' flags will be lost:
Message has been read
Message has been answered
Message is "flagged" for urgent/special attention
Message is "deleted" for later removal by EXPUNGE
Message has incomplete composition (marked as a draft)
If you still want to proceed with the partial restoration, open this file:
and set the SmartRestore parameter value to false.
If the old restoration process is still running, stop it, remove the already-restored content, and re-run the restore procedure. It should finish much faster now.
