Hello, I have created a little cron script that creates a daily tarball from my entire Zope dir. But in order to do this I must stop Zope - create the tarball and then start Zope again. I now that Zope will only be down for about 2 minutes or so but customers don't like that :-) So I was wondering if there was a way to do a daily backup without stopping Zope ?

Hi Gitte, I'm not sure you really need to! Are you concerned about backing up Data.fs in the middle of a write? Because of the way FileStorage works objects are added to the end, the worst case is that you'd lose the last transaction. However, to be squeaky clean, you could: stop Zope restart Zope in "readonly" mode (./start -r) backup stop Zope restart Zope in "read/write" mode. -steve On Friday, August 10, 2001, at 04:30 AM, Gitte Wange wrote:

Well .... last night I tried to create a tarball from the zope-dir while Zope was running .. and someone accessed our website (Data.fs changed I guess) and tar exited with an error. When I stopped Zope and created the tarball everything went fine ... How while users experience the website if Zope is running i read-only mode ? While it still be working ? Gitte

Well... I've never done it, but I'm guessing it will generate IO Errors when changes are attempted. -steve On Friday, August 10, 2001, at 08:02 AM, Gitte Wange wrote:

This is specific of the tar. Zope does not care if you open the file for reading in the middle of the write. One solution would be a copy of (at least Data.fs) into another directory and backup of this. Since I change my zope via CVS, I only have to backup Data.fs (The CVS repository gets backed up otherwise) HTH Tino Wildenhain
How while users experience the website if Zope is running i read-only mode ? While it still be working ?
