问题 Forgot to make a backup. Now I have harddrive with databases and new system with empty postgres. Can I somehow restore databases? by simple copy of files etc? 回答1: If you have the full data directory of your old postgresql system (and if it was the same version, or differing only in a revision number) you can just try to put it in place of your data directory in your new postgresql installation. (Of course, stop postgres server before doing this). It's basically the same procedure used when

Extracting jpegs from a disk dump

问题 I've got a 16GB memory card off someone that won't load properly (asks to be reformatted). I'm trying to get jpegs off it. I've run dd to dump the contents to a file, which worked splendidly. The file won't mount and be read, so the contents are corrupt in someway. Opening the dump in a hex editor shows that there is data on there, and by looking for the markers for the start and end of a jpeg (FFD8 and FFD9), I've been able to manually extract the first 3 jpegs. Before I go and write some

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. Checking objects: 100% (1265/1265), done. broken link from commit f3419f630546ba02baf43f4ca760b02c0f4a0e6d to tree 29616dfefd2bff59b7fb3177e99b4a1efc7132fa broken link from commit ccfe9502e24d2b5195008005d83155197a2dca25 to tree 0580c3675560cbfd3f989878a9524e35f53f08e9 broken link

How to recover database from MDF in SQL Server 2005?

由 不羁岁月 提交于 2019-12-03 03:54:58
问题 I have an MDF file and no LDF files for a database created in MS SQL Server 2005. When I try to attach the MDF file to a different SQL Server, I get the following error message.

This error could occur if the transaction log file was manually deleted or lost due to a hardware or environment failure. I would like to
