问题 Recently a user of one of my apps reported that all her data was lost when she updated the app. I think this is a long shot, but is there anyway for me to inspect her 'documents' folder within the app on her iPad? Or a way for her to send me her document folder so I can see what's going on and hopefully salvage the data? 回答1: If she is a fairly technically capable user, you could have her use PhoneDisk http://www.macroplant.com/phonedisk/ to mount your app's sandbox and inspect the Documents

问题 tl;dr: is it possible to recover HEAD^ 's tree if it is deleted and not pushed beforehand and if everything else is intact? I accidentally deleted part of my .git . I'm not entirely sure what's missing. Upon discovering that git push didn't work, I ran a git fsck : Checking object directories: 100% (256/256), done.

问题 I made a wrong update query in my table. I forgot to make an id field in the WHERE clause. So that updated all my rows. How to recover that? I didn't have a backup.... 回答1: Sorry man, but the chances of restoring an overwritten MySQL database are usually close to zero. Different from deleting a file, overwriting a record actually and physically overwrites the existing data in most cases. To be prepared if anything comes up here, you should stop your MySQL server, and make a copy of the

问题 In my postgesql database, unfortunately I truncate this table mail_group , and the table is delete from the database, how to I get back this table. Kindly help me, waiting for reply. Thanks 回答1: Anyone else in the same situation: immediately stop your database with pg_ctl stop -m immediate (the immediate is important, you need to simulate a crash and prevent a checkpoint) then do not restart it. .

问题 Is there a way to create a file in Linux that link to a specific iNode? Take this scenario: There is a file that is in course of writing (a log maybe) and the specific file is deleted but a link in the dir /proc is still pointing at it. In this case we need not a bare copy of it but an hard link to it so we can have the future modifications and the most last modification before the process close and the system delete it. If we have the iNode number is there a way to achieve this goal? 回答1:

问题 Our client's server got corrupted and the drives containing NDF and LDF files were gone. The only drive that survived was the one with MDF files. There were no backups of any sort. They recovered the database, which I know just a gist of, by creating new database (from a old database, I guess) and applied bcp utility to copy data over to the new one. But, they would not release the information how they actually recovered. So, I was just curious to find how it is possible to recover data from

问题 I altered a stored procedure and unknowingly overwrote some changes that were made to it by another developer. Is there a way to undo the changes and get the old script back? Unfortunately I do not have a backup of that database, so that option is ruled out. 回答1: The answer is YES , you can get it back, but it's not easy. All databases log every change made to it. You need to: Shutdown the server (or at least put it into read-only mode) Take a full back up of the server Get a copy of all the
