In theory, if you are not dependent upon use of ZODB versions, consideration of DirectoryStorage may be warranted: it has a 'snapshot' mode that defers new transactions to a temporary holding directory while the main directories containing objects are frozen, allowing you to use standard Unix backup tools like tar/cpio+find for incremental backup and/or replication. It should be noted that DirectoryStorage also includes a backup.py script that uses the storage to get a list of changed files that will work as a replacement for using the 'find' command. Once the full and/or incremental backup is complete, the storage can leave snapshot mode and all transactions in the holding directory are flushed into the main directory (asynchronously, I think). http://dirstorage.sf.net Cheers, Sean -----Original Message----- From: Jens Vagelpohl [mailto:jens@zope.com] Sent: Sunday, October 27, 2002 7:54 AM To: Ausum Studio Cc: zope@zope.org Subject: Re: [Zope] Re: [Zope-CMF] Using XRon to backup my portal i have never seen it that the original file is "frozen" during that copy operation. i have successfully copied Data.fs files up to 5 GB (on linux) without any indication that the website had any trouble. if you can verify that the original turns "read-only" during the copy then that could be a windoze-only thing. jens On Sunday, Oct 27, 2002, at 01:05 US/Eastern, Ausum Studio wrote:

Just a quick question about it:

What happens to the ongoing transactions? I'm using W2K and from other large-file copies I've done it looks like the original file is frozen to changes, unless it's completely uploaded in memory.

Do I need to stop Zope in order to allow the OS to perform the copy?

Thanks in advance,
