Restore Time Machine backup from Synology

If you find yourself in a situation where you need to restore your Mac from a Synology NAS, you will find out pretty soon after you enter the recovery mode, that backup disk is not visible in recovery window. Steps need to be executed in order Recovery process to find NAS.

Best practise is to name Time Machine shared folder on Synology without spaces. Second, if you are using a password with spaces, which I strongly suggest from security point of view, always put it between ' ' example: 'This is my password'.

  1. Enter the OS X recovery mode by holding Command +R (when Mac restarts and display is grey)
  2. When window with options is presented, select Utilities from the bar and select Terminal
  3. In Terminal use following commands:
  • Cd /Volumes
  • ls /la
  • Create a folder to mount Synology to by typing mkdir synology
  • Now mount your NAS by entering following command
mount -t afp afp://admin:password@ synology
Where admin is your username with administrative rights, password is password for that account (use ' ' if you are using spaces) and TimeMachine is the name of your TimeMachine share on your NAS.

After it mounts, check if it is really there

- cd synology
- ls -la

Now you need to mount sparsebundle by using hdid (hard drive image driver)

- hdid nameOfThebundle.sparsebundle

Enter the password if needed (if your drive or backup was encrypted)
Now quit the Terminal and select Restore from Time Machine. Your backup on NAS should be visible now. Just follow the instructions on screen.

Netscaler vs Exchange 2019 "time out during ssl handshake stage

If you are using Citrix Netscaler as load balancer in front of Exchange 2019 server you must know this: Microsoft Exchange 2019 is secured by default and allows only TLS 1.2. Therefore default schannel settings are as follows (using IISCrypto tool from Nartac Software): While Citrix Netscaler offers following Cipher Suites: TLS_RSA_WITH_AES_256_CBC_SHA TLS_RSA_WITH_AES_128_CBC_SHA TLS_DHE_RSA_WITH_AES_256_CBC_SHA TLS_DHE_RSA_WITH_AES_128_CBC_SHA TLS_DHE_DSS_WITH_AES_256_CBC_SHA TLS_DHE_DSS_WITH_AES_128_CBC_SHA TLS_RSA_WITH_DES_CBC_SHA TLS_RSA_EXPORT_WITH_DES40_CBC_SHA TLS_RSA_EXPORT_WITH_RC2_CBC_40_MD5 TLS_DHE_DSS_WITH_DES_CBC_SHA TLS_DHE_DSS_EXPORT1024_WITH_DES_CBC_SHA TLS_DHE_DSS_EXPORT_WITH_DES40_CBC_SHA TLS_DHE_RSA_WITH_DES_CBC_SHA TLS_DHE_RSA_EXPORT_WITH_DES40_CBC_SHA TLS_RSA_EXPORT1024_WITH_RC2_CBC_56_MD5 TLS_DH_anon_WITH_DES_CBC_SHA TLS_DH_anon_WITH_AES_128_CBC_SHA TLS_DH_anon_WITH_AES_256_CBC_SHA TLS_DH_anon_EXPORT_WITH_DES40_CBC_SHA Now, you will fi

Exchange Admin Center language

Depending on your computer language settings, Exchange Admin Center can take those and open in a language you actually don't want to use. You'll Google that this can be changed if administrator/ admin user has mailbox by openening OWA settings and changing Regional parameters. But usually Admin user does not have mailbox or you don't want her/him to have it. You will search again and find that you can add mkt=en-US (as an example) to the URL of the Exchange Admin Center (https://yourexchangehostname/ecp?ExchClientVer=15&mkt=en-US) Third option you have is opening Internet Explorer settings (I am using Windows 2016) Click languages Click Set Language Preferences Add language you want to use by clicking Add language Use Move up or Move Down options to put desired language on top Close Internet Explorer Open it again and login again to Exchange Admin Center

Free/Busy missing - Cloud to On-Premises

We had a problem where M365 users could not retreive Free/Busy information from on-premise Exchange server. Hybrid setup was run and everything was working fine except this. After research I found out that TargetSharingEpr is the way to look at. There are many sites out there that are pointing to the same setting but only Set-OrganizationRelationship is used to change the value. The problem is, this value is available for two commands: Set-IntraOrganizationConnector Set-OrganizationRelationship While we changed the value in  Set-OrganizationRelationship it didn't work until we changed the value in  Set-IntraOrganizationConnector too. By default it should work with just  TargetAutodiscoverEpr but for us it didn't. Finally we ran this command on Intra Organization Connector which is used from Cloud to On-prem:  Set-IntraOrganizationConnector -TargetSharingEpr And it worked.
