Hi, i am doing exactly that since last Thursday. I have about 1.6TB in Maildirs and an huge number of small files. I have to say it is awfull slow. Backing up a directory with about 190GB of Maildirs took "Elapsed time: 1 day 14 hours 49 mins 34 secs". On the other hand i have a server with Documents and images (about 700GB) took much less time. All the Servers are virtuall Enviroments (Virtuozzo).
Any Idess would be appreciated.

And when you have many incrementals in a row while restoring, you end up seeing many duplicate messages, that have been deleted or moved during these incrementals. It'll be better in Bacula 3.0, I guess :) -- Silver ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
