The time it takes to restore from a backup depends on the size of your backup and the speed of your Wi-Fi network. If you still need help, check below for your issue or the alert message that you see.
This article provides solutions for common issues that you might experience during Microsoft SQL Server backup and restore operations, and provides references to further information about these operations.

Backup and restore operations are I/O intensive. Backup/Restore throughput depends on how well the underlying I/O subsystem is optimized to handle the I/O volume. If you suspect that the backup operations are either stopped or taking too long to finish, you can use one or more of the following methods to estimate the time for completion or to track the progress of a backup or restore operation:
The SQL Server error log contains information about previous backup and restore operations. You can use these details to estimate the time that's required to back up and restore the database in its current state. The following is a sample output from the error log:
You can measure backup and restore throughput information by using the "Device throughput Bytes/sec" and "Backup/Restore throughput/sec" performance monitor counters. For more information, see SQL Server, Backup Device Object.
If you're using either third-party software or database maintenance plans to do simultaneous backups, consider whether you should change the schedules to minimize contention on the drive to which the backups are being written.
A SQL Server backup can't be restored to an earlier version of SQL Server than the version at which the backup was created. For example, you can't restore a backup that's taken on a SQL Server 2019 instance to a SQL Server 2017 instance. Trying to do this will cause the following error message to be generated:
Error 3169: The database was backed up on a server running version %ls. That version is incompatible with this server, which is running version %ls. Either restore the database on a server that supports the backup, or use a backup that is compatible with this server.
If you receive error messages that indicate a file issue, this is symptomatic of a corrupted backup file. Examples of errors that you might experience if a backup set is corrupted include, but are not limited to, the following:
To prevent these errors, enable the Backup CHECKSUM option when you run a backup to avoid backing up a corrupted database. For more information, see Possible Media Errors During Backup and Restore (SQL Server).
You can also enable trace flag 3023 to enable a checksum when you run backups by using backup tools. For more information, see How to enable the CHECKSUM option if backup utilities do not expose the option.
Either of these scenarios can occur if the SQL Server service account doesn't have Read and Write permissions to the folder that backups are being written to. Backup statements can be run either as part of a job step or manually from SQL Server Management Studio. In either case, they always run under the context of the SQL Server Service startup account. Therefore, if the service account doesn't have the necessary privileges, you receive the error messages that were noted earlier.
SQL Server provides a Virtual Backup Device Interface (VDI) tool. This API enables independent software vendors to integrate SQL Server into their products to provide support for backup and restore operations. These APIs are engineered to provide maximum reliability and performance, and to support the full range of SQL Server backup and restore functionality. This includes the full range of snapshot and hot backup capabilities.
For versions that are earlier than SQL Server 2012, make sure that the SQLWriter service is started and that the startup account is set to Local System. Also, make sure that the NT AUTHORITY\SYSTEM login exists in SQL Server, and that it's part of the Sysadmin server role of the instance to which backups are run.
Make sure that SqlServerWriter is listed when the VSSADMIN LIST WRITERS command is run at a command prompt on the server that's running SQL Server. This writer must be listed as a writer and should be in the Stable state to enable VSS backups to finish successfully.
"Back Up and Restore of SQL Server Databases": This topic covers the concepts of the backup and restore operations for SQL Server databases, provides links to additional topics, and provides detailed procedures to run various backups or restore tasks (such as verifying backups, and backing up by using T-SQL or SSMS). This is the parent topic about this subject in SQL Server documentation.
If you have accidentally deleted Proloquo2Go, it is likely still possible to recover your customizations. If you have set Proloquo2Go to automatically save backups to Dropbox or Google Drive, you can restore one of these. Otherwise, it may still be possible to restore an automatic iCloud backup.
If you have been running Proloquo2Go 5 or higher and the device is connected to the internet, you likely have an automatic iCloud backup saved. Automatic iCloud backup saves the most recent backup from each user on each device linked to your iCloud account.
If you have been saving backups using iTunes File Sharing or Connect to Computer/WiFi, you can also import and restore these files into Proloquo2Go. Please see the following support articles for instructions:
To restore from an internal backup, tap Options* in the bottom toolbar. Then, go to Backup > Restore from Backup. Find a backup from before you noticed the changes. To restore it, tap Restore on the right side of its row. If the backup is from a user with a different name than the one you are currently in, Proloquo2Go will ask which user you want to restore it to.
Internal backups are only stored inside Proloquo2Go. If you accidentally delete Proloquo2Go or the device is damaged, you will also lose these backups. Additionally, Proloquo2Go only keeps the eight most recent backups from each user. To be safe, we recommend regularly saving backups outside the app. You can have Proloquo2Go back up to iCloud, Dropbox, or Google Drive. Or, you can save backups to your computer using iTunes File Sharing or Connect to Computer. For instructions, please see the Protect, Recover, and Share Vocabulary Support section.
Most iPhone users could benefit from erasing their device. Whether their iPhone is plagued by annoying bugs or weighed down with years upon years of data. A restore is like a tune-up for your iPhone software, making it quick and snappy again.
Typically, people recover their data from an iCloud or iTunes backup after restoring their iPhone. This is why you might hear restore from iCloud or restore from iTunes. The process involves a restore and then recovering a backup.
Apps, messages, settings, and even your health data (provided you chose iCloud or an encrypted computer backup) comes back. After recovering all the data, your iPhone looks exactly like it did before you erased it.
You should wait for the back up to complete before restoring your iPhone.How do I make a backup using a computer?iTunes used to be the only way you could back up an iPhone to a computer. But Apple removed iTunes with macOS Catalina; now you need to use Finder to back up an iPhone.
My quick question is if I create a Windows system image on a Dynamic Disk (Microsoft recommends against it, but it's my only option right now) and then move the backup files to a network share, will I still be able to restore from it when I need it?
There are several issues. First, it seems that Windows 10 does not support system image backup, but provides it for backward compatibility with Windows 7. I can access it in Control Panel through Control Panel\System and Security\Backup and Restore (Windows 7)
When restoring a system image from this volume, the disks on your computer cannot be formatted to match the layout of the disks in the backup. To have full restore functionality, select a volume on basic disk as your backup location.
I can't change my Dynamic Disk to a Basic Disk now because I have to reformat it, so I tried to store the image on my NAS. Now when specifying the network share to save the image, it fails with this error: "the specified backup disk cannot be found." There are lengthy threads on Microsoft forums about this issue with no working answer. This StackExchange post suggests to use a folder without network access restrictions, but that still didn't work for me.
Also make sure "Block Level Backup Engine Service" is running. If there is an existing backup in the backup location, Windows will use it for block-level copying of the files, which will greatly speed up the job.
Note that if you want to backup also files and folders, in Windows 10 the File History app is recommended over the old Backup and Restore. But for creating system images as of now (version 1803) there is no new solution available by Microsoft.
If you backed up system image, you'll see a "WindowsImageBackup" folder in your backup drive. If you also chose to backup files, you will also have a "MediaID.bin" file and a folder with the name of your computer that you can open to restore your files.
To restore the system image you will need a System Repair Disc that you can create from Backup and Restore (Windows 7) window by clicking on "Create a system repair disc" on the left. But don't do that because you need an ISO. Go to Windows download page and download the Media Creation Tool. Run it and create the installation media to an ISO file (Windows.iso).
Now the question is, how to restore from the VHD file using system repair disc? I haven't tried it yet, but my plan is to use Hyper-V and attach a physical hard disk plus the system image VHD, and Windows.iso as DVD drive. Boot from the DVD and follow System Image Recovery to restore from the attached VHD into the physical HDD. 2ff7e9595c
