Restore too slow

Thread solved

Hi,

I have a PC with fast HDD for tib files and fast SSD for Backup Source.

Now I have to do a large restore and it is very slow. My CPU has 4 cores.

Are the IO Buffers too small?

Heinrich, sorry but there are a lot of variables that can be involved in any backup and/or recovery operation.

What you are restoring?  Disks & Partitions or Files & Folders.

How are you restoring?  From within Windows or when booted from rescue media.

How is the backup HDD connected?  Internal SATA drive, external USB drive, network drive.

If recovery / restore is performed using bootable rescue media, this is a dedicated process and will use all available system resources.  The rescue media should be created to match the CPU architecture of the host system for best performance, i.e. 64-bit or 32-bit.

If recovery / restore is performed from within Windows, then other applications, including security / antivirus etc can be involved, as well as competition for resources.  Any disk recovery should be performed from rescue media rather than from in Windows if the OS drive is involved, as a restart would be required and this will use a small Linux environment, whereas the recommended rescue media uses WindowsPE media.

In addition to @Steve Smith's observations, the when using a backup scheme using incremental backup, the greater the number of incremental backups since the last (relevant) full backup the longer the recovery is likely to be.

Hi,

I tried to restore from 176 GB Windows, but there ara many Acronis threads and the AMD 4 core CPU is at approx 40%. VLC takes 100%, but I don't like 100%. Explorer is slow enough. I tried to create a linux boot DVD but it is missing a driver for internal SATA. I tried WinPE but it has no credentials to find my Win 10 home and there is no *.inf in my downloaded driver.

Many thx in advance

Heinrich, can you expand on exactly what you are restoring here and where you are restoring it from?

My current understanding is that you are trying to restore a backup of your Windows disk drive (176GB) and that this is stored on a different Windows 10 system being accessed across your local network?  Is this correct?

What type of internal SATA drive are you restoring to here?  It seems strange that the Linux media doesn't have support for an internal drive?  Is this a single drive or is it a RAID array that requires RAID drivers to be installed in the rescue media in order to recognise the array as a 'single drive'?

I would recommend taking a look at the MVP Custom PE Builder tool and using this to create your rescue media, as this has more options to allow injecting support for RAID and NVMe type drives. 

You can also download a copy of the free Double Driver tool which can extract the required device drivers from your installed devices, i.e. network drivers etc.

Heinrich,

You mention VLC taking 100% CPU usage, is VLC Video Lan Media player?  If yes what version are you running?  The latest version is 3.0.11, if your is an older version I suggest you install the latest version in hope to address the high CPU usage.

You also state that WinPE has no credentials for your Win 10 Home.  WinPE nor Linux has credentials by default.  A user must provide such credentials when prompted.  If network problems persist then I suggest if possible that you copy the entire contents of the folder that contains the backup files you wish to restore to another device such as a USB HDD and recover from that device locally.  You must have ALL files from the folder that contains the backup for this to work an HDD with a few TB of free space may be required.
