Fixing CrashPlan Upgrade to 4.8.2

published:
I recently got a E-Mail from Crashplan indicating that my NAS is not backing up data for more then 3 days. Since I don't check all the other backup state e-mails, this definitely got my attention


An they weren't wrong. My local installation did not connect to the NAS anymore and the java process was also missing in the Synology's task manager.

Staring the package in the "Package Canter" didn't work, but at least the log was somehow interesting

According to the discussion on the package owners blog post, this seems to be an issue with a missing cpio.

Seems to have been a lack of cpio again.
copied cpio to /usr/bin
Uninstalled
Reinstalled
Restarted
Connected client and logged in
Now running 4.8.2, synchronising to CP Central and my laptop is backing up to the NAS.

See: https://pcloadletter.co.uk/2012/01/30/crashplan-syno-package/comment-page-47/#comment-149189.

Based on the additional comments on the mentioned blog-post and my own experience I followed the following steps to get it back to business again.


1. Before you start

Good News! The following process takes approximately 15 mins and your backup is back in business. Your backup-sets get restored. However, you need the following information while reinstalling CrashPlan
  • Account Name / E-Mail
  • Account Password
  • Data Encryption Key if any
  • Manual Max Memory Adjustments if any (see /volume1/@appstore/CrashPlan/syno_package.vars)
2. Copy the missing cpio

I have no idea what this binary is used for, but it seems there is a huge history about problems with this file in combination with Synology and Crashplan. I just copied the file from the package to my /etc/bin-Folder.

sudo cp /volume1/@appstore/CrashPlan/bin/cpio /bin/cpio

2. Uninstall via Package Manager

Just use the UI and uninstall the package. I did not experience any issues here and the process completed with "This package has been successfully uninstalled."

3. Install Again

Keep using the Package Manager to reinstall the Crashplan Package

  • Accept the Licence Agreement 
  • Select the "Java Runtime Environment Selection" as you did on the previous installation 
  • Uncheck: Run after installation!

4. Trigger the Upgrade

When you first start the package, it will find an update that should now be able to be applied to your system. To keep you updated during this process open a SSH connection an use the command tail -f /var/packages/CrashPlan/target/log/service.log.0 to show the current log in your console.
After you're set-up, run the package in the "Package Manager"

You should be able to see a couple of messages regarding the upgrade

After approx. 2 minutes the log should show one last message "Service stopped normally"

[05.06.17 11:26:57.974 INFO  Thread-1       com.backup42.service.CPService] Service stopped normally

5. Start Service

Now let's start the package again and the "Failed to run the package service" will be shown. Wait for approx. 1 min to start over again, the log-window will again start issuing the latest log messages. One message should be something like

READY!    Unauthorized    Listening ports are PEER=4242/4247, CPD=4243, HTTP=4244

6. Setup UI again

Which means we now have to get the ui-token again from /var/lib/crashplan/.ui_info. You can do this on the console by typing cat /var/lib/crashplan/.ui_info.

Copy the token to your local UI installation as it is described in "Step 1: Copy the authentication token" on https://support.code42.com/CrashPlan/4/Configuring/UsingCrashPlanOnAHeadless_Computer

7. Activate

When firing up the UI you will need to login again using your CrashPlan credentials and all Backup sets configurations where restored. Don't enter you Data Key if you need to adjust the Data Deduclibation and Memory Limits.

8. Check Data Deduplication Settings

Open the file /volume1/@appstore/CrashPlan/conf/my.service.xml and navigate to the <backupSets>-Node. Every backup set should still have the <dataDeDupAutoMaxFileSizeForWan>1</dataDeDupAutoMaxFileSizeForWan> entry.

9. Check MaxMemory limit

Validate of the file /volume1/@appstore/CrashPlan/syno_package.vars still contains your settings before the upgrade. The example below shows 1.5GB of RAM
#uncomment to expand Java max heap size beyond prescribed value (will survive upgrades)
#you probably only want more than the recommended 1024M if you're backing up extremely large volumes of files
USR_MAX_HEAP=1536M

MANIFEST_PATH_SET=True

Use Bodmer TFT_eSPI Library with PlatformIO

published:
Image
If you start playing around with TFT on your ESP8266 or ESP32, you will arrive at the excellent TFT_eSPI Library by Bodmer . It's not only magnitudes faster than the Adafruit driver , it's also comes with support for a wide range of display drivers. Test results of the TFT_eSPI library Unfortunately it has one catch: The library is not really ready to be included as a library in your projects as it requires adjustments in the library itself. While it's not uncommon to define your settings with #define directives, this library expects you to patch files to configure it . The official way goes like this Locate the library folder (Windows would be Documents\Arduino\libraries\TFT_eSPI ) and create your own setup in the library sub folder User_Setups To use your configuration, patch the file User_Setup_Select.h  to include your configuration This has obviously some disadvantages. At latest when you wan't to update the library or work with different screens at the same tim

Migrating from Arduino IDE to Visual Studio Code to PlatformIO

published:
Image
Like every other beginner on ESP8266 I started with my first steps in the official Arduino IDE. I was impressed by the simplicity and easy to use examples that were build-in to the UI. Also the simple UI made it easy to start in uncharted land, especially for someone that did never develop embedded firmware. The library manager let me install additional libraries to play around with, and it also mostly worked. Standard Arduino Editor (IDE) Needless to say, I missed a lot of the features that I was used to from more powerful IDE's like IntelliJ or Visual Studio. I think even Visual Basic 6 had a better IntelliSense support than the Arduino IDE. In fact, Arduino IDE has none. Also, the lack of a dependency management (for libraries) makes it really hard to share code between multiple peers, as you have to manually install the correct version of a library in the global libraries folder. Guess what happens if you use different versions? But overall the Arduino IDE is a g
