问题 The problem is this: t0: Insert is made into my database t1: Delete is executed t2: Full backup is made t3: Transaction log backup is made How can i recover the deleted record after t3 (which is now)? I want the database in a state between t0 and t1. The log level was Full. Edit: I have already run DBCC LOG(DB-Name, 3), but the log seems to be truncated.

问题 I'm trying to write a PHP script to backup a MySQL database: if ( $db_resource = mysql_connect($db_server, $db_username, $db_password, $db_newlink) ) { if ( mysql_select_db( $db_name, $db_resource ) ) { $backupFile = $db_name."_".date( "Y-m-d-H-i-s" ).".gz"; $command = "mysqldump --opt -h ".$db_server." -u ".$db_username." -p ".$db_password."

问题 I'm managing a reasonably large SQL Server database. Some tables contain data that are business-critical and must be backed up offsite daily. But we also have other (read-write) tables that take up about half the size of the database that aren't business-critical. What I would like to do is something like this: Primary filegroup: Tables A, B, C --> daily backup Secondary filegroup: Tables D, E, F --> monthly (or occasional manual) backup When I tried to test this, I got errors while trying to

问题 I have an Azure Cosmos DB and I need to delete all the resources from this subscription. Is there any way to take a backup offline from the portal? 回答1: You can use Data Migration Tool suggested on Automatic online backup and restore with Azure Cosmos DB article to do the same.

The recommendation is to open a support ticket (e.g. via Azure Portal) or call Azure Support to streamline the backup/restore strategy and to request Azure

问题 Sorry if it is a duplicate, but I tried to find an answer here, and nothing helped. So I've read heroku articles like this and this. I was able to save a dump file, which I've created with pg:backups capture command. Uploaded it to s3 and tried to restore it with: heroku pg:backups restore DATABASE 'https://s3-eu-west-1.amazonaws.com/somebucket/uploads/tmp/b011.dump' But it just do not work! In console it logs: Unknown database: https://s3-eu-west-1.amazonaws.com/somebucket/uploads/tmp/b011

问题 I need to take a schedule backup without a specific table in sql. Because if I take a backup with that table it will take long time. I need to exclude one table from backup. Is it possible? Without that table all tables and data should be there in the database. 回答1: You can setup a separate file group for this one table, apart from the PRIMARY file group. This will give you the ability to create a backup that omits your large table. Below is an example that steps out the process. 1) Create a

问题 Thankfully, Google announced the export logic from cloud Datastore. I would like to set up schedule-export in my platform. However, it's not Python, but Java. So I need to use cron.xml and Java logic to design this logic. Is there any reference to design Datastore export logic (cloud_datastore_admin.py) in Java? Especially, I need to transform this part in Java app = webapp2.WSGIApplication( [ ('/cloud-datastore-export', Export), ], debug=True) https://cloud.google.com/datastore/docs/schedule

问题 I have three different databases for my different environments ( hsprd , hstst , hstrn ). hsprd is my production environment with live data. Every so often, a request comes through to restore production data to hstrn or hstst . I typically run this command (after stopping, then dropping the db): db2 restore db hsprd taken at 20140331180002 to /dbs into hstrn newlogpath /dbs/log/hstrn without rolling forward; When running this, I receive this message: SQL2537N Roll-forward is required

问题 I have ArangoDB running locally with databases, collections, data and graphs from several different projects in it. I'd like to back up everything so I can rebuild my system. I know how to do a backup of a single database, but because I have a bunch I'm hoping to do this in one shot.
