Git for Windows Notes
use git bash for rudimentary stuff, fix the default prompt:
export PS1="\[\033[01;32m\]\u@\h[\033[0:34m\] \w \$\[\033[00m\]"
add git usr bin to path so you get openssh not putty.
/c/Program Files/Git/usr/bin:
ssh-add and ssh-agent work the same as on *unix
git wants to use the ssh in your path which is probably putty not openssh.
so you add /c/Program\ Files/Git/usr/bin/ to your path and that doesn't work.
Then you:
David@Enkidu[ ~/Intro_ml_w_Python $git config --global core.sshCommand "/c/Program Files/Git/usr/bin/ssh.exe" David@Enkidu[ ~/Intro_ml_w_Python $git config -pull C:/Program Files/Git/usr/bin/ssh.exe: C:/Program: No such file or directory fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists.
And that also doesn't work.
So you copy C:\Program Files\Git to C:\Git and then:
git config --global core.sshCommand "/c/Git/usr/bin/ssh.exe"
and that works. Sigh.

ERROR - One of the parameters or options provided is unexpected: systemState. Se

the syntax below.
Syntax: WBADMIN START BACKUP
[-backupTarget:{<BackupDestinationVolume> | <TargetNetworkShare>}]
[-include:<VolumesToInclude>]
[-allCritical]
[-user:<UserName>]
[-password:<Password>]
[-noInheritAcl]
[-noVerify]
[-vssFull | -vssCopy]
[-quiet]
Description: Creates a backup using specified parameters. If no parameters
are specified and you have created a scheduled daily backup, this command
creates the backup by using the settings for the scheduled backup.
Parameters:
-backupTarget Specifies the storage location for this backup. Requires a
hard disk drive letter (f:), a volume GUID-based path in the
format of \\?\Volume{GUID}, or a Universal Naming Convention
(UNC) path to a remote shared folder
(\\<servername>\<sharename>\).
By default, the backup will be saved at: \\<servername>
\<sharename>\WindowsImageBackup\<ComputerBackedUp>\.
Important: If you save a backup to a remote shared folder,
that backup will be overwritten if you use the same folder to
back up the same computer again. In addition, if the backup
operation fails, you may finish with no backup because the
older backup will be overwritten, but the newer backup will
not be usable.
You can avoid this by creating subfolders in the remote shared
folder to organize your backups. If you do this, the
subfolders will need twice the space of the parent folder.
-include Specifies the comma-delimited list of items to include in the
backup. You can include multiple volumes. Volume paths can be
specified using volume drive letters, volume mount points, or
GUID-based volume names. If you use a GUID-based volume
name, it should be terminated with a backslash (\). You can
use the wildcard character (*) in the file name when
specifying a path to a file. Should be used only when the
-backupTarget parameter is used.
-allCritical Creates a backup that includes all critical volumes (critical
volumes contain the operating system files and components) in
addition to any other items that you specified with the
-include parameter. This parameter is useful if you are
creating a backup for bare metal recovery or system state
recovery. Should be used only when the -backupTarget
parameter is used.
-user If the backup is saved to a remote shared folder, specifies
the user name with write permission to the folder.
-password Specifies the password for the user name that is provided by
the parameter -user.
-noInheritAcl Applies the access control list (ACL) permissions that
correspond to the credentials specified by -user and
-password to \\<servername>\<sharename>\WindowsImageBackup
\<ComputerBackedUp>\ (the folder that contains the backup).
To access the backup later, you must use these credentials or
be a member of the Administrators group or the Backup
Operators group on the computer with the shared folder.
If -noInheritAcl is not used, the ACL permissions from the
remote shared folder are applied to the
<ComputerBackedUp> folder by default so that anyone with
access to the remote shared folder can access the backup.
-noVerify Specifies that backups written to removable media (such as a
DVD) are not verified for errors. If you do not use this
parameter, backups saved to removable media are verified for
errors.
-vssFull Performs a full backup using the Volume Shadow Copy Service
(VSS). Each file's history is updated to reflect that it was
backed up. If this parameter is not used WBADMIN START BACKUP
makes a copy backup, but the history of files being backed up
is not updated.
Caution: Do not use this parameter if you are using a product
other than Windows Server Backup to back up applications that
are on the volumes included in the current backup. Doing so
canpotentially break the incremental, differential, or other
type of backups that the other backup product is creating.
-vssCopy Performs a copy backup using VSS. The history of the files
being backed up is not updated. This is the default value.
-quiet Runs the command with no prompts to the user.
Example: WBADMIN START BACKUP -backupTarget:f: -include:e:,d:\mountpoint,
\\?\Volume{cc566d14-44a0-11d9-9d93-806e6f6e6963}\

Limiting Bits Regedit way
reference: https://superuser.com/questions/1039229/limit-bandwidth-used-by-windows-update
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\BITS
Create a DWORD value called EnableBITSMaxBandwidth with a value of 1; that tells BITS that there are settings to look at. Create DWORD values called MaxBandwidthValidFrom and MaxBandwidthValidTo, each containing an hour of the day from 0 to 23. (For example, 8 is 8:00 AM, and 17 is 5:00 PM.) These actually don't matter a lot in this case, but I told you about them for completion's sake.
Create two more DWORD values called MaxTransferRateOffSchedule and MaxTransferRateOnSchedule. Give each of them the maximum rate of transfer in Kbps. Note that you may need to switch to Decimal entry mode to see the value as normal humans think about numbers.
Summary:
DWORD EnableBITSMaxBandwidth 1 DWORD MaxBandwidthValidFrom [0-23] DWORD MaxBandwidthValidTo [0-23]
DWORD MaxTransferRateOffSchedule 64 ( in kilobytes ) DWORD MaxTransferRateOnSchedule 64 ( in kilobytes )
Regedit file:
Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\BITS] "EnableBITSMaxBandwidth"=dword:00000001 "MaxTransferRateOnSchedule"=dword:00000040 "MaxTransferRateOffSchedule"=dword:00000040
