Hi, We think we know the answer to this, but we?ll ask the question anyway.
We?re trying to backup a 10GB live running database ?as-fast-as-we-possibly-can? without stopping updates coming in. The updates come every 2-3 mins, and write a chunk of data in. We can?t really stop the database updates, well we can but we don?t want to. 1. We had a quick look to see if we could copy the sqlite file over in the short interval between updates but sadly cp simply wasn?t fast enough. We get around 3GB copied before an update happens, which basically renders the cp useless. 2. If we use the command line sqlite <filename> .dump > <backupfilename> it works, but its very slow. 3. Using the Sqlite C API works but is also very slow. 4. We don?t have the option of an LVM snapshot as the file system is in a Container <sigh>. So is there any other method of doing a quick snapshot? Failing that, our solution will be to stop any updates for the duration of the cp command, and then restart the process afterwards. Its not the end of the world but it would have to be done out of normal working hours. This is going to become a bigger problem for us as the database will only get bigger so any advice welcomed. Thanks Rob
