What directories to backup on ESXi apart from the VMs? – Server Fault

Posted by jpluimers on 2017/08/18

What directories to backup on ESXi apart from the VMs? – Server Fault [WayBack]:

You may want to look at purpose-built VMware backup tools. You will be very disappointed if you treat an ESXi host like a Linux/Unix server.

Use the VMware backup commands [WayBack] from a separate station, and you’ll be left with a nice configuration tarball. I would find another approach for the actual VM backups.

Edit: Host-based example

vim-cmd hostsvc/firmware/sync_config
vim-cmd hostsvc/firmware/backup_config

This stores the config in /scratch/downloads:

# vim-cmd hostsvc/firmware/backup_config
Bundle can be downloaded at : http://ip.of.esxi.host/downloads/52fd67ba-2fdf-9876-6651-46c3da638f1a/configBundle-centaur.ewwhite.net.tgz

Twitter image size suffixes – via: Making silly #latex jokes is much more fun than doing final tweaks in my thesis on #coeffects…

Posted by jpluimers on 2017/08/18

Twitter stores images on twimg.com in various sizes.

You specify the size by adding a colon plus suffix to the URL. No colon plus suffix means a default size.

Suffixes you can use see to come from the media entity in Entities in Objects | Twitter Developers:

  • thumb
  • small
  • medium
  • large

There is one undocumented size: orig

The default size seems to be medium.

Examples (full images below):

media entity observed size URL
thumb 150×150 https://pbs.twimg.com/media/CiMNh9rWEAAdM6Q.png:thumb
small 340×325 https://pbs.twimg.com/media/CiMNh9rWEAAdM6Q.png:small
medium 600×573 https://pbs.twimg.com/media/CiMNh9rWEAAdM6Q.png:medium
(none) 600×573 https://pbs.twimg.com/media/CiMNh9rWEAAdM6Q.png
large 1024×979 https://pbs.twimg.com/media/CiMNh9rWEAAdM6Q.png:large
orig 1600×1529 https://pbs.twimg.com/media/CiMNh9rWEAAdM6Q.png:orig

Thanks to Thomas Petricek [WayBack] who poked fun last year on Twitter [WayBack] at both LaTeX and O RLY (the image meme [WayBack], not the text meme)
