MacBook Time Machine backup to WD My Book Live "Time Machine completed a verification of your backups on 'WDx'. To improve reliability, Time Machine must create a new backup for you."

My setup for MacBook Air backup was Time Machine backing up to WD My Book Live 3T hard disk. Every month or so, I got an error stating "Time Machine completed a verification of your backups on 'WDx'. To improve reliability, Time Machine must create a new backup for you."

90 GB of data to backup? Again?! I tried everything, from changing the name of the computer (because ' in name can make some problems), removing all the security (absolutely not advisable ;) ) just to check things out and... nothing. Whatever I did the error kept coming out.

The solution:

Sell WD My Book Live and buy yourself a Synology NAS. It costs more but the difference is soooooo big you will not regret it. No more monthly full backups, no more network lags and you get additional apps you can use.

And this is not a commercial :D

UPDATE: After 3 months of backup to Synology NAS no failures, no verifications,... works like a charm.

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
