OS Updates
On a monthly basis, Quality NOC Cloud engineers review all recommended patches made available by operating system software vendors
Studies have been performed in accordance with GCP standards.- Injectable alprostadil buy viagra online.
. A subset of these patches and updates are identified by the OS vendor as Critical or Important to installed operating systems. The most recent version of our OS is given these updates and is then re-certified by Quality NOC before it is made available to be implemented with new server builds.
Managed Server Updates
As a part of making a server managed, more updates may automatically be applied to the server. Different Linux distributions and Windows are supported. Automatic updates can be pre-agreed with the customer and discussed in weekly status meetings.
Dedicated Server and Public clouds
Dedicated Servers and Public clouds platforms can be managed by our team of system administrator, Microsoft Windows servers and Linux distribution are supported. We have deep experience installing new applications, scripts and applying system updates, or upgrades on Red Hat, CentOS, Ubuntu, Debian, and other linux distributions. We can coordinate with your operations or devops team and schedule downtime, and do previous snapshots befoer patching or updating your OS or applications.
Extend your operations, DevOps or development team
We do weekly meetings with our customers, we can also do short daily meetings monday to fridays and continue chat on Slack/Wire/Skype, with your operations team, devops, or developers establishing a very fluid communication and reporting about progress and/or incidents.
One of the tasks we enjoy most is to provide Linux Patch maintenance to our customers.
We have many years of experience doing patch maintenance and OS upgrades on Ubuntu, Debian, Red Hat, Cent OS, and other Linux flavours. OS and Application Maintenance
You should periodically update your Linux operating system (OS) and its applications. Install Operating System and Application Patches/Updates
We focus on security patches, go trough security articles and follow up possible impact on our server managed customers.
For website owners it is very important to keep your WordPress site updated, that include plugins, themes, word press version, etc
We can follow up Windows updates news and see how new updates could impact in the running services and inform our customer before applying.
A good backup plan is essential in order to have the ability to recover from
Human errors
RAID or disk failure
File system corruption
Data center destruction and more.
Here you have some suggestions:
Important features the backup software should have:
Open source software – You must use software for which the original source code is made freely available. This ensures that you can recover your data in case vendor/project stopped working on software or refused to provide patches.
Cross-platform support – Make sure backup software works well on the OS deployed on all desktop and server operating systems.
Data format – Open data format ensures that you can recover data in case vendor or project stopped working on software.
Autochangers – Autochangers are nothing but a variety of backup devices, including library, near-line storage, and autoloader.Autochangers allows you to automate the task of loading, mounting, and labeling backup media such as tape.
Backup media – Make sure you can backup data on tape, disk, DVD and in cloud storage such as AWS.
Encryption datastream – Make sure all client-to-server traffic will be encrypted to ensure transmission integrity over the LAN/WAN/Internet.
Database support – Make sure backup software can backup database server such as MySQL or Oracle.
Backup span multiple volumes – Backup software can split each backup (dumpfile) into a series of parts, allowing for different parts to existing on different volumes. This ensures that large backups (such as 100TB file) can be stored on larger than a single backup device such as disk or tape volume.
VSS (Volume Shadow Copy) – It is Microsoft’s Volume Shadow Copy Service (VSS) and it is used to create snapshots of data that is to be backed up. Make sure backup software support VSS for MS-Windows client/server.
Deduplication – It is a data compression technique for eliminating duplicate copies of repeating data (for example, images).
Commercial support – Open source software can provide community based (such as email list or fourm) or professional (such as subscriptions provided at additional cost) based support. You can use paid professional support for training and consulting purpose.
Reports and alerts – Finally, you must able to see backup reports, current job status, and get alert when something goes wrong while making backups.
Bacula – Client/server backup tool for heterogeneous networks
I personally use this software to manage backup and recovery across a network of computers including Linux, OSX and Windows. You can configure it via a CLI, GUI or web interface.
Operating system : Cross-platform
Backup Levels : Full, differential, incremental, and consolidation.
AMANDA is an acronym for Advanced Maryland Automatic Network Disk Archiver. It allows the sysadmin to set up a single backup server to back up other hosts over network to tape drives or disk or autochangers.
Amanda: Open Source Backup
Amanda is the most popular open source backup and recovery software in the world. Amanda protects more than a million servers and desktops running various versions of Linux, UNIX, BSD, Mac OS-X and Microsoft Windows operating systems worldwide.
Operating system : Cross-platform
Backup Levels : Full, differential, incremental, and consolidation.
Data format: Open (can be recovered using tool such as tar).
BackupPC is a high-performance, enterprise-grade system for backing up Linux, WinXX and MacOSX PCs and laptops to a server’s disk. BackupPC is highly configurable and easy to install and maintain.
Operating system : Linux/Unix and Windows
Backup Levels : Full and incremental (rsync+hard links and pooling scheme)
It is an easy to setup open source client/server backup system, that through a combination of image and file backups accomplishes both data safety and a fast restoration time.
UrBackup also continuously watches folders you want backed up in order to quickly find differences to previous backups. Because of that, incremental file backups are really fast.
Your files can be restored through the web interface, via the client or the Windows Explorer while the backups of drive volumes can be restored with a bootable CD or USB-Stick (bare metal restore). A web interface makes setting up your own backup server really easy.
Currently there are over 10,000 running UrBackup server instances (with auto-update enabled) with some instances having hundreds of active clients.
Operating system : Linux/FreeBSD/Unix/Windows/several Linux based NAS operating systems. Client only runs on Linux and Windows.
Other open source backup software for your consideration
The Amanda, Bacula and above-mentioned software are feature rich but can be complicated to set for small network or a single server. I recommend that you study and use the following backup software:
rdiff-backup – Another great remote incremental backup tool for Unix-like systems.
Burp – Burp is a network backup and restore program. It uses librsync in order to save network traffic and to save on the amount of space that is used by each backup. It also uses VSS (Volume Shadow Copy Service) to make snapshots when backing up Windows computers.
SafeKeep – SafeKeep is a centralized and easy to use backup application that combines the best features of a mirror and an incremental backup.
DREBS – DREBS is a tool for taking periodic snapshots of EBS volumes. It is designed to be run on the EC2 host which the EBS volumes to be snapshoted are attached.
Old good unix programs like rsync, tar, cpio, mt and dump.
Conclusion
I hope you will find this post useful to backup your important data. Do not forgot to verify your backups and make multiple backup copies of your data. Also, RAID is not a backup solution. Use any one of the above-mentioned programs to backup your servers, desktop/laptop and personal mobile devices.
