3 years agoYesterday I killed the partition on my hard drive whilst screwing around. Like any good IT person I had made a backup that day before I started (2 actually a full and an incremental).
I confidently inserted my Veeam endpoint recovery CD excited that I could show off my new backup program and began a Bare Metal Restore with my latest incremental backup. After an hour it was done and I booted the machine up expecting to get back to work. NOPE 'No operating system detected..Ctrl + Alt + Delete'
A bit annoyed I decided to use the Full that I had made about an hour before the incremental. I restored that backup to my hard drive and booted up to the same message. Words were said that should not be heard by children or those with weak stomachs.
At this point I thought that I may have a bad hard drive so I checked SMART on the drive but it was green across the board.
I remembered a third backup I had on a different drive and decided to try it. Same results. So I began trying to fix the partition from a Windows recovery CD and command line. Success! But after seeing the glorious windows logo I was stopped by a BSOD 7E on PCW.sys I gave up at this point.
So here I am on a reloaded hard drive having to reinstall all my programs. Fuming and cursing Veeam and computing in general.
The lesson (a bit obvious) test a backup solution before you use it. Even if everyone on the internet says its better than tits.
Edit: All hail /u/BigBlueBoner 'The resolution was to boot into WIN PE/Veeam Recovery CD and go to command line to delete the PCW.SYS. After that it booted into Windows, but I had to reinstall all of the drivers.' That fixed it. Enjoy your gold sir!!
Edit 2: Did a test backup/restore with a separate system and it was successful. I didn't even make new recovery media just used the one I had laying around. Starting to suspect a hard drive issue. May RMA it just to be safe.

There seems to be various JavaScript+browser specific ways of decompressing this, but isn't there some way to transform jsonlz4 files to something

Actually almost all Firefox profile lz4 files are mozlz4 files. It means they have the same 'file format header'.Except one file. I talk about webext.sc.lz4 file. It has
mozJSSCLz40v0010
file header and maybe some sc
packaging to pack group of files to on byte stream.There is a Firefox addon to read or compress .mozlz4 text files mozlz4-edit

Sufficiently persistent Googling for this turns up a lot of solutions, but most of them seem to be either (a) broken by subsequent changes to underlying libraries, or (b) unnecessarily complex (at least to my personal taste), making them clunky to drop into existing code.
The following appears to work at least on Python 2.7 and 3.6 using a recent version of the Python LZ4 bindings:
Of course this does not attempt to validate inputs (or outputs), is not intended to be secure, etc., but if one just wants to be able to parse one's own FF data, it gets the basic job done.
Command line version here, which could be saved in the relevant directory and invoked from the command line as:

Hi Guys, Getting this error on my backup jobs. I've varied my backup proxies from dedicated physical servers, to virtual servers. I've varied my backup targets between the NAS and USB storage. I've pointed redirected my targets from vcenter to directly from the hosts. I've checked for any connected disks that may have been left over from previous jobs (none there). I'm not sure where to go from here.
1/02/2015 12:02:17 PM :: Error: Application is shutting down. Failed to download disk. An existing connection was forcibly closed by the remote host Failed to upload disk. Agent failed to process method {DataTransfer.SyncDisk}.
Has anyone seen it and had any luck getting rid of it?

Morning all,
I have spent the past three months on and off building our image for the summer on Veeam. The capture of the image failed, so I thought fine. I'll just roll back the snap shot and try again. Oh no! You can't do that as the restore fails. I've actually tried restoring other backups offsite (DC and mail server) and they worked without an issue. I don't really want to have to rebuild the image myself as I have spend ages building it. If anyone has any bright ideas I would really appreciate it. A copy of the logs are below and I do have a ticket open with Veeam support (which has now been opened for a week with little help!).
Thanks in anticipation, eddyc
