Backup Exec migration

When I recenty upgraded a backup exec server to x64. I needed to do a completed reinstall so I needed a way to migrate my selection lists and jobs. I found this method was very straightforward and worked perfectly! The idea is to copy the entire database straight over.

1. Stop all backup exec and sql services on the old server

2. Copy catalogs and Data catalogs from Backup Exec directory to a temporary location.

3. Do the reinstallation and install backup exec again.

4. Stop all backup exec and sql services.

5. Copy catalogs and data directories onto existing.

6. Start services again.

7. Use beutility and choose Copy Database, pick your newly copied databasefiles from the data catalogue.

8. Use Beutlity to Update configuration for New Media Server Name.

9. Restart.

Some small issues that had to be resolved afterwards…

Devicepools – Backup exec also imported the old devices onto the new installation. This causes conflicts with the deviceids and if the device isn’t the same as before it needs to be removed.

All policies will retarget jobs to All Devices after this so these will need  to be reconfigured.

In my case, there where some B2D-devices that couldn’t be removed from the devicetab. The solution was to remove them directly from the the database table. Open up SQL Management Studio and remove the old devices from table dbo.devices . Problem solved.

Selection Lists shows only All Resources – image

Issue with selection lists being empty, both when editing a existing lists and creating a new. Though through View Selection Details you could actually see the selections on a existing list. Also when trying to show the User Selection Lists this error was displayed image

This was resolved by changing the System logon Account under Network> Logon Accounts to better reflect the new server.

Wireless (in)security

For the past year a contact of mine has been carrying a wireless network sniffer around Gothenburg and outskirts. Hidden in plainview on his smartphone, steadily going wherever he went. Adding network after network. All while noting their coordinates, securitylayers and names. Now when the imagenumber of AP’s in his database has exceeded 11 000 he decided to share this data with me to try to make sense of the information and try to present the statistics in an orderly fashion.

Regarding security level it’s comforting to know that WPA is, by far, the dominating encryptionmethod.

11097 Access Points was detected. Of these there was 3468 using WPA2 Personal, 3561 using WPA Personal, 489 using WPA2 Enterprise, 119 using WPA Enterprise, 1706 using WEP and 1751 using no security at all.

Using no security can sometimes be justified. It might be a guestnetwork or it might be network with some form of authentication mechanism like a Radius-server or something like that. Therefore we’re not gonna read to much into the fair number of open networks in our fair city.

WEP-security however, it rarely justified. One reason might be that your Wii gamingconsole doesn’t support any higher encryption than WEP. That was actually true when I bought my console several years ago but I find it hard to belive they haven’t fixed that yet.

Another common reason noted is that the ISP is delivering their equipment with WEP-encryption predefined! This although their equipment still supports WPA2. With some ISP you can’t even manage your own network equipment. You have to call them over the phone (in this decade?) and ask them nicely to raise your wireless security to something that can’t be cracked in 4 minutes.

Very pretty boot analysis tool

While I’ve previously used BootRacer to get a general idea of my computers boottime I’ve now come across a much better tool. Sure Sysinternals autoruns is the perfect tool for monitoring your boot processes it just doesn’t give all the information. Enter Soluto Boot Analysis. This great tool gives you an overview of solutoexactly how long each application takes to start and gives you the option to delay it or pause. If you want to remove it completly it’ll have to be done the old fashioned way. It also gives you overall information of the application, how many Soluto users worldwide is using this app, and whether not they’ve opted to pause it or not. It’s also carrying a pretty interface that’s kind of cool. Try it out!

Easy way to go from dvd to usb

Reinstallation of systems is something I do on a pretty frequent basis. Problem is that I pretty much left disk-readers behind me. to much work overall, an unnecessary expense and not mention: very oldschool.

The other day I came upon a very handy tool from Microsoft that I just can’t understand why they doesn’t promote any better. The tool of the hour is Windows 7 USB/DVD Download Tool.

Contrary to the name, you really need to download your own ISO files to use this handy software. The point is that the software prepares an USB-stick to be bootable from and moves files, creates bootpartitions and whatnot. Something, I for one, thought was a very distracting process. Not mention that I usually bounce from XP to 7 and this usually messes with my bootpartitions immensly.

This tool saves me time. thats enough for me.

Download it and try it out!

Utbytt disk till SSD

Innan: Seagate Barracuda SATA2 disk
Efter: Intel SSD something something

Vid sidan är min nuvarande Windows boottid.

Tog nu ingen innan, men belive you me, det tog över en minut så skillnad är det iallafall!
