Re: How to restore Slide resources ?
Hello ! Sorry, I have just noticed that my explanations are not very clear... I will try to re-explain :-) What I wanted to say is that I think that we could save and restore the ENTIRE Slide content and metadata just by saving the content and metadata root path. Usefull if the Slide backend crashes... At the University of Rennes 1 we intend to use a SAN(NAS) for the Slide backend. This SAN makes snapshots everyday of each file/directory so that a user can restore its documents up to 1 week ago. But with Slide, to restore just one part of the tree (for example a user homedir), I am not sure that we could just restore one directory (and attached metadata) and restart the server. Some French universities are waiting for this kind of functionnalities to use Slide in a production use. Hope it is more clear. Thanks for your help, Regards, Thomas Max Pfingsthorn a écrit : Hi!

RE: How to restore Slide resources ?
Is this not possible with the filesystem store? I would have thought that collection properties are stored within the respective directory? The only thing you would have to do to hot-restore then would be to kick out all nodes below and including the restored one from the slide cache in the extended store. Next time they are accessed, they will be loaded again from the actual store (the filesystem). Some programming is required though. How does that sound? I know it doesn't actually solve your one-click-backup question, but it would be cool to just manipulate the physical data on disk, click, and be "restored"... That would work well with your NAS.

RE: How to restore Slide resources ?
Hello Thomas, I'm not answering your question, but a while back I though at the same problem: how to backup and restore slide's content. Before I discover that it's enough to backup the txtStore content, I though that I would need to create a tool that would download all content and metainfo in the configured stores, and create a 'proprietary' backup file with that content. I mean proprietary because, there isn't such thing as slide's backup file, or a tool to backup/restore slide's content at runtime (maybe I'm wrong here... I do recall someone talk about this at late 2004). If you specify and implement this tool, and the file's content, you could include the backup/restore of a single collection as well. Problem with this approach: it must download the content witch can be a problem if it's done at a wrong schedule, that is, it's not very scalable. Hope this helps, Miguel Figueiredo -Original Message- From: Thomas Bellembois [mailto:[EMAIL PROTECTED] Sent: quarta-feira, 29 de Março de 2006 13:16 To: Slide Users Mailing List Subject: Re: How to restore Slide resources ?

RE: How to restore Slide resources ?
Here is how we do redundant storage. We extended the Tx* stores with a "Store Manager" that implements all the methods and uses the original Tx* filesystem xml code. But our Store Manager looks in a registry and also calls a secondary store based on the path and event being processed. This secondary store then has full access to the updates of both descriptors (metadata) and content. We use the secondary stores for integration with external systems by writing an adaptor between the slide store interfaces and the external system's interfaces. For redundant storage we have a JXTA Secondary store that raises an advertisement of a change to either metadata or content, and that advertisement is picked up by other slide repositories that are registered and participants in the JXTA P2P cloud and then they asynchronously either apply the change directly from data in the advertisement or connect back to the changed repository to pick up the change. Because the secondary stores are mapped we can have some content synchronized in this way while other content is not. Michael Oliver CTO Alarius Systems LLC 6800 E.

RE: How to restore Slide resources ?
That assumes someone is using an all TxtStore, all JDBCStore, all something. If you are using a heterogenous set of stores, synchronization of the different stores during a backup is a problem. We use an Oracle DB for all of our storage so we can do a database backup, but we're actually considering doing a split Oracle/TxtStore backend and then backups will become very entertaining. The post about replication, JXTA, et al sounds like an interesting solution. Does anyone else have any suggestions? -Original Message- From: Thomas Bellembois [mailto:[EMAIL PROTECTED] Sent: Wednesday, March 29, 2006 9:18 AM To: Slide Users Mailing List Subject: Re: How to restore Slide resources ?

RE: How to restore Slide resources ?
Hello Thomas, You are right, that way you wouldn't need to create such a tool - in fact, it seems it is what Michael Oliver is talking about. In our case, we use the *bindings* extension of the TxStore witch stores the metainformation and content somewhat differently and very difficult to follow by human eyes -> no directory structure, it's just one folder with thousands of small files with sequencial numeric names with relations with each other... as I said, very difficult to follow by human eyes. The tool to implement would make transparent the way the stores persist information. In fact, you could use it with other webdav servers :) Best regards, Miguel Figueiredo -Original Message- From: Thomas Bellembois [mailto:[EMAIL PROTECTED] Sent: quarta-feira, 29 de Março de 2006 15:18 To: Slide Users Mailing List Subject: Re: How to restore Slide resources ?
