Backup – Clear Backup logs and Catalog

To start with a clean Windows Backup  Logs and Catalog, (usually when a Backup Disk has failed and not longer usable).

  1. To remove the Catalog run: wbadmin delete catalog
  2. Remove the logs, In the Eventviewer – Applications and Services – Microsoft – Windows – Backup, right click on Operational and select Clear Log

 

The above will completely remove your Backups so should only do this if those backups are no longer required.
We would always recommend offsite backup and not to USB Hard Drives as they are prone to failure

Windows 10

For those many that have asked. I have not received the Windows 10 Update, Why. Without going into all the technical stuff.

Use the Manual Update https://www.microsoft.com/en-us/software-download/windows10

Make sure you have plenty of time free, many hours.

If you have an earlier version of Eset Antivirus or Endpoint, I would recommend uninstalling it first. Once the upgrade is completed. Then re install.

Synology Raid Rebuild – Speed up the rebuild process

Telnet to the Synology NAS, login in a root.   (You may need to enable Telnet Server first)

Raid Stats Command
cat /proc/mdstat

Default Raid Values
cat /proc/sys/dev/raid/speed_limit_max
200000
cat /proc/sys/dev/raid/speed_limit_min
1000

Improve Rebuild Speed  –  increase the speed_limit_min value.
echo 40000 > /proc/sys/dev/raid/speed_limit_min

check speed with
cat /proc/mdstat
Max speed on my DS1812+ with DSM5.1  was just under 40000K/sec
So 3TB Disk took approx 20hrs to rebuild

Remove a corrupt User Profile

1. Rename the profile Directory   c:\users\login name  i.e Login_Name.bak

2. Run Regedit, find the login name from the sub keys in  HKLM\SOFTWARE\Microsoft\Windows NT\ CurrentVersion\ProfileList

and rename with a .bak  i.e   S-1-5-21….

Look in each one for ProfileImagepath that matches the one you renamed in point 1.

Don’t forget to backup the Registry before you start, as getting this wrong could damage your Operating System.
