Re: On Yojimbo and Time Machine
Coming to think of it, there would be a way to back up Yojimbo with Time Machine: you just need to create a sparse bundle disk image with Disk Utility, put your Yj DB on that and make the Yojimbo folder in ~/Library/Application Support/ an alias to the mountpoint of the image in /Volumes. Finally, write a little Automator script to mount the image, e.g. at startup, and start Yojimbo through the script after mounting the image. Time Machine can back up the Yj DB in pieces of 8 MB, because you chose sparse bundle disk image!. Basically, it is much the same as you might have already for Mail - e.g., I use an encrypted sparse bundle disk image for my mail folder, which I mount before starting mail, requesting the password and then starting Mail - and a nice way to safely store your e-mail, too. -Florian On 15.02.2008, at 7:37, Jan Erik Moström wrote: Rhet Turnbull [EMAIL PROTECTED] 08-02-14 15.58 I would never use a backup solution that didn't run on live data.

Re: On Yojimbo and Time Machine
This is getting offtopic for Yojimbo so I won't continue past this email. I appreciate your comments Jan and I do understand the issue of data of data consistency. The only way to completely avoid that is to take the system completely down for backup and either run the backup in single user mode or better yet, run the backup in target disk mode without even the OS running. But I won't do that because of convenience nor will most other users. I don't ever close applications or log off my machine unless a software update forces me to and I suspect there are many more like me. Most people don't backup because it's inconvenient which is one of the main things that Apple was trying to address with Time Machine. Time Machine also has the added advantage of provided checkpoints throughout the day that you can roll-back to (at least for specific files). I'd much rather take the very small chance of data inconsistency than accept the inconvenience of offline backups. Now to get it back to Yojimbo so we're not completely off topic ;-) If Yojimbo stored records as separate files and kept metadata and/or index data in smaller DBs then the backup regime would only have to backup those files that had changed instead of the entire xxxMB sqllite file that Yojimbo uses now. I believe that would decrease the risk of inconsistency as opposed to the case now, where Yojimbo could write the the large database file while the backup is trying to copy it. And finally, once users get used to the power of Time Machine's rollback capability, they'll demand it. There are several times I wish I could have rolled back a Yojimbo record (this is exacerbated by Yojimbo's lack of read-only records which has allowed me to accidentally edit Yojimbo data that I didn't intend to).

Curious, why is this bad? In the case of a backup the monolithic solution is extremely annoying. As a good analogue, consider Apple Mail. Each email is its own document. When my system backs itself up, each new message is backed up cleanly with a very small upload. In the case of Yojimbo, instead of pushing only those files that have changed, the backup takes much longer since the entire file needs to be copied repeatedly even if only a small change/addition occurred. I hope that BareBones and/or Apple gets this fixed soon. Requiring the user to have two separate backup plans is unacceptable. Hmmm, I would always be skeptical of a backup solution that runs on live data. By having individual files, the problem you rightly note above becomes less pronounced since the vast majority of the backup would happen to files that are closed. Obviously some sort of main db file which organizes these smaller files would still suffer from the problem, however in most cases these sorts of files could be rebuilt anyway since the important data (ie: the individual files) would be available. I use LifeAgent as my backup solution since it seems to work pretty well over wireless NAS (such as Airport extreme) and it tracks changing files in ~real time. For a laptop, it seems to work pretty well. Unfortunately though, my nightly backup over a wireless often consists of a the huge Yojimbo databasewaiting...waiting...you get the picture. -Lance -- -- This message is sent to you because you are subscribed to the mailing list yojimbo-talk@barebones.com.

Re: On Yojimbo and Time Machine
I was unaware of the restriction regarding Yojimbo and Time Machine. Fortunately I haven't upgraded to Leopard yet (but had planned to do so now that the 10.5.2 update is out and in fact have the Leopard box sitting on my shelf). Time Machine was one of the driving reasons for me to upgrade to Leopard but Yj is an app I use everyday so this is an unacceptable situation. It is very regrettable that Apple would adopt a standard like CoreData only to make it incompatible with one of their flagship features. Then again, Yojimbo's habit of storing everything in a monolithic database has been one of my (few) critiques since Yojimbo was released. I hope that BareBones and/or Apple gets this fixed soon.

Re: On Yojimbo and Time Machine
Curious, why is this bad? 1. Backup...the entire DB file (mine is hundreds of MB) needs to be backed up. I backup everyday, both to external drive and offsite. That means the large Yojimbo file needs to be backed up every day, taking up unnecessary bandwidth and disk space. 2. Data integrity...if the database file gets corrupted, you could lose all your data instead of only 1 item. The Yojimbo competitor Together (http://reinventedsoftware.com/together/) does it this way, storing each record in a separate file. 3. Time Machine...this breaks things like time machine which offers roll-back capability. Contrast the way that Microsoft Outlook (not sure about Entourage) and Mail.app store mail messages. Outlook puts everything in a single database file. Mail.app stores each message in a separate file (but utilizes a database file for indexing). I have 3GB of email which means that Outlook would require backing up a 3GB file wheres for Mail.app, I only need to backup the new message files and the small index file. Hmmm, I would always be skeptical of a backup solution that runs on live data. I would never use a backup solution that didn't run on live data.
