Backup regime for cloud clients
Backup regime and security measures
Due to the fact that so much data is loaded onto our servers and the systems are cloud-based we have to take certain safety measures to keep the data safe from hackers and safe from fires and systems failing.
The first step in
order to ensure we have the data and to keep the data safe and up to date is to
make backups on a regular basis.
See below the steps to ensure the safety of the data.
On the windows
machines 3 different backups are made:
1. For the Printers and their settings
2. For all the users
3. For all the exe files.
The Printers and the Users are Aron’s – these are image based backups
Between each night there is a down time for the data where backups are made
between 10-12 every night. These backups
take about 12 minutes to run.
The backups are done every single day to ensure that no data gets lost and
should a practice lose data and need to
recover it, we can retrieve it for them form our backups.
When back up are being made the Cu-SQL will do a dump to a RAR file between
10-12 at night. Just after the backups has been made. 2 dumps are done per
client file.
Usually 2 backups are kept for each client, one for just after month end and
one for the start of each month. But
there are currently backups for about 2 weeks currently on our databases.
Example:
There are currently 3 data centres where we have several servers running
Randview, Isando and Xneel
Each server takes all the data that has been replicated and share it with
different servers in the data centres.
Each server has a hard drive which is the main
hard drive and a backup hard drive that replicates each other. Should one hard
drive decides to stop working for some or other reason then the backup hard
drive will have all the data on it. As it replicates constantly.
Ransomware has been installed on the Windows machines. It is not that easy to access our data or
hack our systems. To get onto our systems you will need the address then a user
with a 16 digit passwords.
NTLM is in place to stop the guessing of users and passwords and block most of
the IP’s from other countries.
The data is stored as
ZFS files. ZFS is an advanced file
system, with the following interesting features.
- Pooled storage
-Copy-on-write
-Snapshots
-Data integrity verification and automatic repair
-RAID-Z
- Maximum 16 Exabyte file size
- Maximum 256 Quadrillion Zettabyte storage
