Create New Destinations for JetBackup


This article covers how to create New Destinations for JetBackup. Basically, clients choose to store at least one copy of backups locally and additional copies in at least one or more remote destinations. Remote destinations are usually slower than local destinations to backup and restore from due to bandwidth requirements. With this in consideration, many clients choose to store at least one copy of backups locally and additional copies in at least one or more remote destinations.

Whatever backup destination option(s) you choose, please make sure that your destination path is secure and has the appropriate privileges.


How To Secure Local Backup Storage ?

Prior to adding a destination to JetBackup, we advise securing the backup directory, so that only the allowed users can access that folder.

In order to do that, please connect to the destination via console/GUI, and make the directory in which you want to store your backups.

For example:

$ mkdir [-p] /mnt/backup_vol/jetbackup

Then we advise securing that destination so only one user can access it's content (except root):

$ useradd <jetbackup>
$ chown jetbackup:jetbackup /mnt/backup_vol/jetbackup
$ chmod 700 /mnt/backup_vol/jetbackup

Right now only two users that can access this directory are root and jetbackup.

Please search online, how to secure a backup folder for your particular file system (EXT, NTFS, FAT, etc..) on your system (Windows, Linux, macOS, BSD, etc..)

Monitor MongoDB with Nagios XI - How to perform this ?


This article covers  how to monitor a MongoDB server with Nagios XI using the MongoDB Server Configuration Wizard in order to monitor the health of your server. The

wizard supplies checks to monitor the following: number of queries per second, memory usage, the number of databases on the server, and percentage of free connections available.


To Connect to MongoDB with the appropriate privileges:

Connect to mongod or mongos with the privileges specified in the Prerequisites section.

The following procedure uses the myUserAdmin created in Enable Access Control:

mongo --port 27017 -u myUserAdmin -p 'abc123' --authenticationDatabase 'admin'

The myUserAdmin has privileges to create roles in the admin as well as other databases.


To Modify Access for an Existing User in MongoDB:

  • You must have the grantRole action on a database to grant a role on that database.
  • You must have the revokeRole action on a database to revoke a role on that database.
  • To view a role's information, you must be either explicitly granted the role or must have the viewRole action on the role's database.

Exclude Files from Backups in DirectAdmin - How to do it ?


This article covers how to Exclude Files from Backups in DirectAdmin. 


User ability to skip paths from their tar.gz backup files in DirectAdmin.

i. New optional file:

/home/username/.backup_exclude_paths

where User can add paths to this file that they wish to have skipped from their backup.

The format of the file must be relative to /home/user and should not include a "/home/user" prefix.

2. New default internal directadmin.conf setting:

allow_backup_exclude_path=1

can be disabled by setting it to 0 and restarting DA.

A sample line in the .backup_exclude_paths would look like:

domains/domain.com/awstats

so that the path:

/home/username/domains/domain.com/awstats

is skipped from the backup.

This will add:

--exclude-from=/home/username/.backup_exclude_paths

Just after the -C /home/username option in the creation of BOTH the home.tar.gz and the user's backup tar.gz.

So using the feature will truly exclude the path, regardless of if it's in /home/user/domains, or /home/user/*.

As you may have noticed, the option uses tar's exclude-file option.

This supports patterns, eg:

*.gz

So you have skip those types of files, regardless of what path they're under.

Manage Transaction Log File during Data Load - Do it Now


This article covers how to manage transaction log files in SQL Server for our customers. A transaction log is a file – integral part of every SQL Server database. It contains log records produced during the logging process in a SQL Server database.

The transaction log is the most important component of a SQL Server database when it comes to the disaster recovery – however, it must be uncorrupted.

The only way to truncate the log, so the space can be reused, is to perform a SQL transaction log backup. Therefore the most common reason for a transaction log file to have grown extremely large is because the database is in the FULL recovery model and LOG backups haven't been taken for a long time.


How do I stop a transaction log from filling up?

1. To keep the log from filling up again, schedule log backups frequently. 

2. When the recovery mode for a database is set to Full, then a transaction log backup job must be created in addition to backing up the database itself.


To fix a transaction log for a database is full:

1. Backing up the log.

2. Freeing disk space so that the log can automatically grow.

3. Moving the log file to a disk drive with sufficient space.

4. Increasing the size of a log file.

5. Adding a log file on a different disk.

Duplicity restore full backup


This article will guide you on steps to perform a Duplicity-restore full backup. #Duplicity is an efficient #backup application.

#rsync is a protocol built for Unix-like systems that provides unbelievable versatility for backing up and synchronizing data. It can be used locally to back up files to different directories or can be configured to sync across the Internet to other #hosts.

Incremental Backup captures only the changes made since the last incremental backup. Saves both time and #storage space, and ensures that your backup is up to date. Differential Backup captures only the changes made since the last full backup, not since the last differential backup.

When a normal or full backup runs on a selected drive, all the files on that drive are backed up. This, of course, includes system files, application files, user data — everything. The downside of normal backups is that they take a very long time to run, and in some cases this is more time than a company can allow.

To Use Duplicity with GPG to Securely Automate #Backups on #Ubuntu:

1. Install the Prerequisite Packages.

2. Download and Install Duplicity from Source.

3. Create SSH Keys.

4. Create GPG Keys.

5. Run an Initial Test.

6. Create Your First Backup.

7. Restore a Backup.

How to securely back up your Linux Ubuntu Centos and Debian Server


#Backup and #restore refers to technologies and practices for making periodic copies of data and applications to a separate, secondary device and then using those copies to recover the data and applications—and the business operations on which they depend in the event that the original data and applications are lost.

#rsync uses what is called a delta-transfer algorithm which compares files from source and destination and sends only the differences between them.


To automatically backup #files and directories in Linux:

1. archive the content. Backing up your files using tar is very simple using the following command: # tar -cvpzf /backup/backupfilename.tar.gz /data/directory.

2. create backup script. Now let's add tar command in a bash script to make this backup process automatic.


#Rsync, or Remote Sync, is a free command-line tool that lets you transfer files and directories to local and remote destinations. 

Rsync is used for mirroring, performing backups, or migrating data to other servers.

Backing up file systems means copying file systems to removable media (such as tape) to safeguard against loss, damage, or corruption. 

Restoring file systems means copying reasonably current backup files from removable media to a working directory.

Data losses can be a very frustration encounter for a server owner. To avoid such catastrophic situations in losing your website data, it is very important to do a regular backup for your server and website.
