HELIOS "dt" Tools Sync Erfahrungen von Daniel Scheuber
 ·  Translate
 
«HELIOS dt tools» – ein kleiner Praxisbericht aus dem Kundenbereich!


Die Datensicherung auf Disk, Server oder Tape mit externer Lagerung ist die Basis eines professionellen Backupkonzeptes.

Vielfach geht es auch darum, dass zB. 10'000 GB und mehr an Daten einfach im Zugriff auf einem anderen Server-Volumen präsent sein müssen, damit die Apple- und Windows-Anwender selbständig auf eine frühere Dateiversion zugreifen können. 

Es gibt viele Anwendungen die dieses Bedürfnis erfüllen, dazu gehören «Archiware», «Acronis», «Retrospect» oder diverse Synchronisationstools. Allen gemeinsam ist, dass sie bereits für den Vergleich der Daten auf Quelle und Ziel viel Zeit benötigen und so ein Syncfenster schnell Minuten, Stunden oder gar Tage dauert.

Kundentests haben gezeigt, dass dies mit «HELIOS dt sync» massiv verkürzt werden kann. Der Vorteil dieser serverbasierten Synchronisation liegt in der innovativen Vorgehensweise der HELIOS-Entwickler. Die benötigten 7 Sekunden für den Vergleich eines ca. 470 GB-Volumens sind ein klare Ansage um auch in einem grossen Serverumfeld effizient zu bleiben.


Meine Meinung:
«Geschwindigkeit ist das Eine, die zusätzliche 
- Einfache Konfiguration 
- Stabilität im laufenden Betrieb
- Parametrisierte Sync-Steuerung (z.B. Scan-Only-Funktion)
- Leistungsfähige Dateisynchronisierung von Verzeichnissen, Volumes
  und kompletten Festplatten
- Unterstützung von Mac-Ressourcen und Windows-Filestreams
- Datenabgleich von oder auf per NFS gemounteten Speichersysteme
- Mailbenachrichtigung
sind weitere Kriterien die bei «HELIOS dt sync» einfach stimmen!»

Unsere neue VSA bei +speicherguide
 ·  Translate
 
Das Hannoveraner Softwarehaus #Helios Software hat die Virtual-Server-Appliance 2.0 (VSA) veröffentlicht, mit der sich ein virtueller Fileserver für Windows-, Mac-, Web- sowie mobile Anwender schnell aufsetzen lässt. Die Lösung ist eine Linux-basierte VM, die laut Helios alle gängigen Fileserver-Protokolle (NFS, SMB/CIFS, AFP) unterstützt. "Mit Version 2.0 präsentieren wir den neuen Helios Universal File Server UB64, der jetzt auch Unterstützung für NFS-Server und -Clients bietet, und haben das Linux-OS optimiert", sagt Helios-Geschäftsführer #HelmutTschemernjak.

Bundestags-Hack – Artikel von Michael Grandjean
Interessanter Artikel:
https://www.univention.de/2015/06/bundestags-hack-moegliche-hintergruende-und-verteidigungsmethoden/

Wir haben bei HELIOS UB64 die RSA Kennwörter mit privaten Key für jede Serverinstallation eingeführt. Der Key kann auch auf einem USB Stick gespeichert werden und wird nur beim Serverstart genötigt.

Auch uns bei Univention beschäftigt natürlich der Angriff auf die IT-Infrastruktur des Bundestages, der sogenannte Bundestags-Hack. Doch wie kam es dazu?

HELIOS Virtual Server Appliance 2.0 (VSA) available
We are glad that we completed our new VSA. We did  enormous testing and it is ready for deployment at customer sites. VMware and Hyper-V integration is much better and it performs very well. There is no easier way to get our Universal File Server solution including the Linux OS installed into virtualized server environments. We support the entire solution including Linux. Here are some URL's:

Swift – the trendsetter of a modern programming language
With Apple's announcement last week to turn Swift into open source, Swift will likely become the most popular programming language in the future. I believe Swift has potential to overtake C, C++, Objective-C, Java and maybe C-Sharp.

Swift has the advantage that it is a very modern language which compiles to native code and can be mixed with C and Objective-C code. Swift has no Sandbox-VM environment like Java and .NET, therefore everything can be natively called in the OS without bridging between the runtime and the operating system.

This is what developers have been looking for,  right?

+Ralf Schülke, I am sure that C stays here forever. All embedded stuff, device drivers and other low-level programming are C based for a good reason. For example in our firm at HELIOS most software has been developed in C, with Swift we can preserve existing developments and continue with a modern language (Swift) where the overhead is almost non existing. The benefit will be higher productivity, less errors and more self-explaining code for new engineers working on existing code.

PS: Overtake means not replacing,  just getting more popular.

Server backup at light speed
Sometimes we need to think differently; for our new internal servers (based on our Virtual Server Appliance 2.0) we are developing a new backup strategy. Instead of backing up millions of individual files from each server file system, we do a file system snapshot and copy the entire file system as a single ext4 disk image onto a backup RAID. In a second step we put this disk images to an LTO tape.

This is lightning fast and allows easy access by just mounting the disk image on Linux. Optionally, it can be used as a temporary production file system. Ext4 images can even be mounted on Mac and Windows via additional software.

Finally we are working on enhancements of our Tool Server UB64, to completely automate these tasks and backup many servers remotely. I believe this is a pretty good alternative to a conventional backup of individual files.

Any comments?

Apple Music – First Impressions

Last weekend I started to upgrade to iOS 8.4 and test drive the Apple Music app which combines my own music library with Apple Music offerings. I tested it mainly on my iPhone because this is the device for my personal use when I listen to music.

The initial impression is great because I can basically select each artist and all available albums. I can even specify my preferred music (Apple calls it “For you”) and it will suggest music which I may like.

The disillusionment came after my iPhone battery was quickly draining (70%) after 6 hours of streaming music via a WiFi connection and playing via Bluetooth speakers. Fortunately, I had a WiFi connection, because it requires less power than 4G. OK, that’s the drawback of live streaming versus a regular FM radio, where a battery will last almost forever.

Now having access to all music, my next idea was to search for new albums that were published this year. Again, this was not possible because there is only a “New” selection available which does not allow filtering it to, let's say, everything new starting with February 2015. In the list of new offerings I cannot see the release date of the album.

Another idea was to select special rhythms for dancing, e.g. Waltz, Salsa or Cha-Cha, to collect some music for the next dance event. Again, the Music app does not allow searches by rhythm – sad that I am unable to find what I am looking for in the huge offering by Apple Music!

The Music app does not support landscape mode, as far as I recall, even though major landscape support was introduced in iOS years ago.

I will continue to check out the Apple Music service offering and hope that future versions bring the usability enhancements which are most important to me.

PS: Internet music streaming will add high data usage to public WiFi hotspots, and networks in business environments. This will overtake other web traffic many times over, because music streams continuously.

What is your experience?

I will not being using Apple Music. iTunes in general has become an annoyance. That I can't startup my iMac (i7) and get to work but have to wait for iTunes to load speaks to its predatory nature. iTunes has become an byzantine labyrinth of over-featured complexity. I feel I am playing a bothersome iOS game with in-app purchases when I use iTunes. I miss Steve.

OS X El Capitan – Apple locks down your Mac
So far the Mac has been an open system. Customers owning a Mac had the opportunity to run all preferred solutions and even to backup and restore the Mac using third-party Software or Apple delivered software.

Nowadays the Mac gets locked down similar to iOS, where Apple decides which applications get installed and how much access to the operating system gets granted. With Mac OS  X 10.11 system and library folders will be locked to prevent manipulation and allow only Apple to update them. In the past it has been possible to restore an older library version and to backup and restore the operating system manually or using third party solutions. This time is over.

For consumers this may be good for security reasons, however a locked-down system means less freedom, less competition and monopoly by Apple. This cannot be good.

What do you think?

I guess certificate signing of App Store apps will prevent "helper" apps from using the CORED vulnerability (if the parent app is using a certified and protected system process). Anyway, it can be disabled but the more I read about OS X security vulnerabilities the less I'm likely to disable it: http://www.quora.com/Can-someone-elaborate-on-the-OS-X-10-11-feature-called-rootless

Volks-Smartphone – Microsoft Lumia 532

A fully featured smartphone, 3G with 1 GB memory, running Windows Phone 8.1, upgradable to Windows 10 later this year – affordable for everyone.

I tested the Lumia 532 (99 €) smartphone to find out if this phone is a capable smartphone. Can it be a platform that could handle advanced apps? Also of interest is if it could be a possible future platform for our Document Hub and other apps. I compared it with my iPhone 5 which I use daily extensively. Here is a quick list of aspects:

- Phone talk quality is good, speaker phone works loud and clear
- Built-in apps (Browser, Calendar, Mail, etc.) look similar to other smartphones
- Microsoft Office is included, many users prefer it (I don't use Office very much)
- WiFi speed: download: 15 MB/sec, upload: 1.8 MB/sec (iPhone 5 is about 30% faster)
- 3G speed: download: 13 MB/sec, upload: 2.12 MB/sec (iPhone 5 3G is twice as fast)
- Camera takes reasonable pictures in daylight environments
  Bad pictures in slightly dark rooms. (iPhone 5 camera is significantly better)
- Uses Snapdragon 200 QuadCore processor with 1 GB memory (faster than the iPhone 5)
- Flash storage 8 GB (iPhone 5 has 16 GB)
- microSD slot, supports up to 128 GB, a very big plus for the Lumia
- 4" display with 233 ppi, fine for reading web content
  The iPhone 5 with 336 ppi Retina screen has a much better class display
- Replaceable battery, big plus (battery life is about the same as iPhone 5)
- Weight: 136 g (iPhone 5 is 10% lighter)
- Cloud Services: Microsoft offers capabilities similar to Apple
- Video output option: not available (iPhone has multiple output options)
- Power charger: standard micro-USB
- Replaceable cover with different colors, however swapping it it is very tricky/difficult
- App Store: very similar to Apple, however most app vendors don't support Windows Phone

As a summary I can tell you that I am surprised with the performance and capabilities of the Lumia 532. Yes it is a fully featured smartphone for a 100 € price tag (Dual SIM, no lock), which offers everything a regular smartphone user needs. It cannot be compared with my iPhone 5 because iOS and the iPhone are better in many categories and work much smoother in the details. Microsoft Lumia comes with standards which I love and prefer (micro-USB charging port, microSD slot for easy memory expansion and a user replaceable battery). Using this smartphone is very similar to Android because the menu navigation works with “Home” and incremental “Back” steps, which is also logical to users, and hides the fact that different apps are being used. My opinion is that the Lumia 532 is a Volks-Smartphone everyone can afford.

What is your opinion?

PS: A good candidate for HELIOS mobile solutions.

I did long term battery duration testing with the following results:
- About 7 days idle with Wifi turn on
- About 8 days with Wifi off, mobile data on
- About 11 days with Wifi off, mobile data off

I did not do any phone calls but verified the battery status twice a day.

China cheats – 600 mAh battery has only 100 mAh
China schummelt – 600 mAh Akku hat nur 100 mAh

I unassembled five LED garden lamps and found out that the assembled rechargeable NiMH batteries labeled with 600 mAh contain a capacity of 100 mAh only. I recharged all batteries multiple times and the result is identical: only 100 mAh. Last year's LED lamps had a true 600 mAh battery, also older NiCd LED lamps from years ago had a true 600 mAh. Netto retailer needs to implement better quality controls, and the Chinese supplier needs to stop cheating. 

Questions?
