A complete guide to Hadoop Installation that will help you when ever you face problems while installing Hadoop !!
In computing, ZFS is a combined file system and logical volume manager designed by Sun Microsystems, a subsidiary of Oracle Corporation. The features of ZFS include support for high storage capacities, integration of the concepts of file system and volume management, snapshots and copy-on-write clones, continuous integrity checking and automatic repair, RAID-Z and native NFSv4 ACLs. Unlike traditional file systems, which reside on single devices and thus require a volume manager to use more than one device, ZFS file systems are built on top of virtual storage pools called zpools. A zpool is constructed of virtual devices (vdevs), which are themselves constructed of block devices: files, hard drive partitions, or entire drives, with the last being the recommended usage.[7] Thus, a vdev can be viewed as a group of hard drives. This means a zpool consists of one or more groups of drives.
In addition, pools can have hot spares to compensate for failing disks. In addition, ZFS supports both read and write caching, for which special devices can be used. Solid State Devices can be used for the L2ARC, or Level 2 ARC, speeding up read operations, while NVRAM buffered SLC memory can be boosted with supercapacitors to implement a fast, non-volatile write cache, improving synchronous writes. Finally, when mirroring, block devices can be grouped according to physical chassis, so that the filesystem can continue in the face of the failure of an entire chassis. Storage pool composition is not limited to similar devices but can consist of ad-hoc, heterogeneous collections of devices, which ZFS seamlessly pools together, subsequently doling out space to diverse file systems as needed. Arbitrary storage device types can be added to existing pools to expand their size at any time. The storage capacity of all vdevs is available to all of the file system instances in the zpool. A quota can be set to limit the amount of space a file system instance can occupy, and a reservation can be set to guarantee that space will be available to a file system instance.

# Internet Security: Safeguarding Your Digital World
In the contemporary digital age, the internet is a cornerstone of our daily lives. It connects us to vast amounts of information, provides platforms for communication, enables commerce, and offers endless entertainment. However, with these conveniences come significant security challenges. Internet security is essential to protect our digital identities, sensitive data, and overall online experience. This comprehensive guide explores the multifaceted world of internet security, providing insights into its importance, common threats, and effective strategies to safeguard your digital world.
## Understanding Internet Security
Internet security encompasses the measures and protocols used to protect information, devices, and networks from unauthorized access, attacks, and damage. It involves a wide range of practices designed to safeguard data confidentiality, integrity, and availability. Effective internet security is crucial for individuals, businesses, and governments alike, as cyber threats continue to evolve in complexity and scale.
### Key Components of Internet Security
1. **Confidentiality**: Ensuring that information is accessible only to those authorized to access it.
2. **Integrity**: Protecting information from being altered or tampered with by unauthorized parties.
3. **Availability**: Ensuring that authorized users have reliable access to information and resources when needed.
## Common Internet Security Threats
Cyber threats are numerous and constantly evolving. Understanding these threats is the first step in protecting against them. Some of the most common internet security threats include:
### Malware
Malware, or malicious software, is designed to harm, exploit, or otherwise compromise a device, network, or service. Common types of malware include:
- **Viruses**: Programs that attach themselves to legitimate software and replicate, spreading to other programs and files.
- **Worms**: Standalone malware that replicates itself to spread to other computers.
- **Trojan Horses**: Malicious software disguised as legitimate software.
- **Ransomware**: Malware that encrypts a user's files and demands a ransom for the decryption key.
- **Spyware**: Software that secretly monitors and collects user information.
### Phishing
Phishing is a social engineering attack that aims to steal sensitive information such as usernames, passwords, and credit card details. Attackers often masquerade as trusted entities in email or other communication channels, tricking victims into providing their information.
### Man-in-the-Middle (MitM) Attacks
MitM attacks occur when an attacker intercepts and potentially alters communication between two parties without their knowledge. This can lead to the unauthorized acquisition of sensitive information.
### Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) Attacks

3 how to-backup_and_recovery
1. BACKUP AND RECOVERY
ALFRESCO SHARE SERVER
Document Management System
Ubuntu14.04 LTS (Trusty Tahr)
JICA SV K.ADACHI
2. Content
•About Cold Backup
•Alfresco Share Server Stop
•Ready to Backup Device
•Backup Settings
•Backup Alfresco Share Server
•Recovery Alfresco Share Server
3. About Cold Backup(Offline Backup)
• A cold backup, also called an offline backup, is a database
backup when the database is offline and thus not accessible for
updating.
• This is the safest way to back up because it avoids the risk of
copying data that may be in the process of being updated.
• However, a cold backup involves downtime because users
cannot use the database while it is being backed up.
4. Alfresco Share Server Stop
Cold Backup need to stop Alfresco .
• Command is :
• $ cd
• $ alfresco-4.2.f/
• $ ./alfresco.sh stop
5. Ready to Backup Device
Connect backup media device(USB HDD)
Connect USB Media or USB-HDD
The Launcher bar display USB icon
and File explore.
If you use Virtual Box, Click Device
menu of Virtual machine.
Select USB Device and Check USB
media.
6. Backup Settings
Launch Backup(Déjà Dup)
• 1. Click System Settings icon
on the launcher bar.
• 2. Click Backup icon.
Backup software is called Déjà
Dup.
Déjà Dup is a simple — yet
powerful — backup tool
included with Ubuntu.
7. Backup Settings
About Déjà Dup
• Déjà Dup is a simple — yet
powerful — backup tool
included with Ubuntu.
• Déjà Dup’s main screen
summarizes your backup
settings.
8. Backup Setting
Setting Folders to save From the Folders to save pane,
you can easily select the folders
Déjà Dup backs up.
By default, Déjà Dup backs up
your Home directory, ignoring
the Trash and Downloads folders.
How to select holder.
1. Select “+” or “-”
2. Select backup folder on File
explore
9. Backup Setting
Needed Backup Directory is the
following Directory at Least.
1.~/alfresco-4.2.f/alf_data/postgresql
2.~/alfresco-4.2.f/alf_data/contentstore
3.~/alfresco-4.2.f/alf_data/solr/workplace
4.~/alfresco-4.2.f/alf_data/solr/archive
Note:
postgresql is database system.
contentstore is real-data-file
solr/workplace and archive is indexing data.
10. Backup Setting
Setting Storage Location
From the Storage pane, you can select
where Déjà Dup store your backups.
The USB option can back up your data to
an external drive or other local storage
device.
Putting the backup on the same drive as
the original files is a bad idea — you’ll lose
both the backup and the originals if the
drive fails.
11. Backup Alfresco Share Server
Back Up Now
• Once you’ve got Déjà Dup set
up, you can perform your first
back up by clicking the “Back
Up Now” button on the
Overview pane.
12. Backup Alfresco Share Server
You’ll be prompted to password-protect your
backup but you can’t recover it if you forget it.
I recommend Allow restoring without a password.
The backup process may take some time,
but each subsequent backup will be faster.
Déjà Dup performs incremental backups,
which means that it only records the
changes from the last backup.
13. Recovery Alfresco Share Server
•Reinstall Ubuntu
•Configure Server network
•Install Alfresco
•Stop Alfresco Share Server
•Restore Alfresco Share Server
14. Restore Alfresco Share Server
Cold Backup need to stop Alfresco .
• Command is :
• $ cd
• $ alfresco-4.2.f/
• $ ./alfresco.sh stop
15. Restore Alfresco Share Server
• Click the Restore button in
the Déjà Dup window to
start restoring a backup.
• Déjà Dup will automatically
select the folder that you
last backed up to, but you
can select any other folder
that contains a backup.
16. Restore Alfresco Share Server
Next, select the date the backup was
taken.
Déjà Dup restores files to their original locations by
default.
You can also have it restore files to a specific folder
if you don’t want to overwrite the existing files.
17. Restore Alfresco Share Server
You’ll go through the same restore
process.
Restoring Progress is a few time.
