    Came back to an unresponsive host this morning. Luckily, only dev sql boxes on it, and.... Sharepoint.

    It would allow you to connect to console, but vm's were "frozen", Vcentre wouldn't connect to it, and i couldn't connect to it directly either.

    Initiated a reboot from the esxi console, and it sat at "Reboot in progress..." for 20 mins.

    After a boot, seemed to have come back up nicely... *shrugs*

    Monday morning and i'm pretty much the only one here, i'm not too worried about it.

    Luckily all our backups have run without a hitch! Went to disk, then duplicated to our other netbackup disk appliance, then committed to tape.

    Love it when backups work nicely! :)

    Today I learnt that sometimes things do just work! :p First day back, Enterprise Vault rolled over to a new Vault Partition without issue and nothing else was rooted! :thumbup: :D

    Adds "Easter Cryptolocker" to his to do list.

    Sure, If I start encrypting everything now, someone will notice pretty quick...

    BUT... if I do it Easter Friday, nobody will notice until monday, and by then I've got 4 days worth of time, and possibly 4 cycles of nightly backups up the clacker.

    When they are available to you maybe. We use a mixture of VSS and Veeam for quick restores.

    2 GB sql dump into:

    * xz : 31 MB, 15 minutes

    * pxz : 32 MB, 1 minute 15 seconds.

    I just found my new favourite compressor.

    Made me laugh. What a champ.

    I've been using xz for a a few years now. Same family of comressors as 7zip/lzma, and kicks the poop out of anything else for text compression (does a much better job than zip/gzip/bzip2 on binaries too).

    Downside was always the speed - it's slow as an old goat, even on decent processors (and we have A LOT of decent processors).

    I'd been using pigz (parallel gzip) for ages, and it never dawned on me to see if anyone had written a parallel xz. 1.8 seconds of googling later, and there it was.

    Never going back to single threaded long term compression again.

    2016 installed, clustered, dag'd, failed over tested.
    Apparently we'll do the L7 loadbalancer later.

    Just need to build our backup environment, then we can push users to it :D (we have backups for 2013 - but 2016 is on ReFS and shadowprotect is stuck in the 90's or some shit and still doesn't support ReFS).

    Exchange native data protection?

    Is it enough to get a serious look-in? Does it make your anus pucker just thinking about it?

    Backups are coming - I'm just waiting on hardware to build the RPS for CA UDP. No client data is landing on the 2016 Cluster till we have backups.

    Also, *touching all the wood*, i've never ever had an Exchange DB shit itself.

    I have VMware Snapshots, etc.


    Oh, and whilst Outlook 2007 might not be "supported" anymore - it still works, even with Mapi over HTTP turn on...

    TIL office 2016 is officially released, when given a new laptop with windows 10 and office 2016 to evaluate

    Still plenty of bugs. Running non cached exchange mode with inboxes greater than 1k emails.... grinds to a slow chundering halt purely changing folders (this is 1k emails even within folders under inbox. move the emails+folders out of inbox so it doesn't index and it's fine).

    I think it's cute when people say that they're going to "evaluate" the next version of office.

    What, because you're ever likely to reject it in favour of another vendor? :lol:
