But if anyone has any insight on what I might be missing here when trying to open these same files in Zotero, I'd be most grateful for any thoughts. I'm not sure if getting the WFH archive files to open in something like DB Browser is diagnostic for anything. open any of the zotero.sqlite files from the WFH archive directly (e.g., with DB Browser for SQLite), I can open the file and pick through the database just fine there too. open in Zotero a backup Zotero has made and that's still in the data directory (i.e., not one that's been saved/copied from there into the WFH archive), the file opens just fine or And I've made sure I'm also trying to open a WFH archive file made from the same machine.īut in any of these scenarios, the same error occurs whenever I try to use Zotero to read a zotero.sqlite file that's been saved via WFH. I have full access to the directory (see, e.g., here), and no security software shows in Task Manager when I boot Windows into Safe Mode. ensure no security software is preventing Zotero from accessing that directory.īoth of these (I think) check out. ensure I have read and write permissions for the data directory and When I try to open a zotero.sqlite file from the WFH archive even from yesterday (e.g., in Zotero's current ZIPed beta version, portable version, and for good measure, regular stable version), I'm told the "database can't be opened" (in this error message) and that I should But things aren't working that way for zotero.sqlite. And I can pull files back from the archive when needed as if they're simply copies. Normally, WFH seems to just save a straight copy of a given file. Otherwise, if ** an error occurs, an SQLite error code is returned.I realize we can't here try to debug issues with Windows File History (WFH), but I'm coming across an odd issue and wondering if there's anything related on the Zotero side. ** ** If the operation is successful, SQLITE_OK is returned. If ** parameter isSave is zero, then the contents of the database opened by ** pInMemory are replaced by data loaded from the file zFilename.

Is no substitute for reading the API documentation! The remainder of this page contains two C language examples illustratingĬommon uses of the API and discussions thereof. The online backup API is documented here. The effect of completing the backup call sequence is to make theĭestination a bit-wise identical copy of the source database as it Users to continue without excessive delays while a backup of an online Of time when it is actually being read from. To be locked for the duration of the copy, only for the brief periods The copy operation may beĭone incrementally, in which case the source database does not need Original contents of the target database. One database to be copied into another database file, replacing any The online backup API allows the contents of The database file the backup database may be corrupted followingĪddress these concerns. If a power failure or operating system failure occurs while copying.It cannot be used to copy data to or from in-memory databases.Any database clients wishing to write to the database file while aīackup is being created must wait until the shared lock is.However, this technique has the following shortcomings: This procedure works well in many scenarios and is usually veryįast. Relinquish the shared lock on the database file obtained in step 1.Copy the database file using an external tool (for example the unix 'cp'.Establish a shared lock on the database file using the SQLite API (i.e.Historically, backups (copies) of SQLite databases have been created
