They are a type of email apps that facilitates inbox management. Email clients also function as personal information managers, offering tools for taking notes, calendaring, and managing tasks, emails, and contacts. #Em client deduplicator software#This can be activated with the Enable Client Rehydration directive (default = no).Conclusion What Is an Email Client and Why Consider Email Management Software in the First Place?Īn email client is a web browser or desktop interface that helps you manage the emails you send or receive. Configuration of the nf Daemon Storage Feature by BWebįrom the text, your nf must be edited to include the directives: Storage Optional File Daemons Configuration (nf)īacula File Daemons might be configured to hold some deduplication information in order to speed up restores, especially using lower bandwidths. From the bconsole, go to the Configuration Module, Storage Daemon button (middle of the screen) and edit the Storage Daemon Resource:įigure 1. Storage Daemon Configuration (nf)Īs Figure 1, the Dedup Directory and Dedup Index Directory directives must be configured for use by Global Dedup. ![]() #Em client deduplicator driver#Restart bacula-sd and verify if the driver is loaded with a status storage command. E.g.: rpm -ivh bacula-enterprise-dedup-plugin-8.10.86_64.rpm It should be installed in the same Bacula Storage Daemon machine. Installationĭedup Driver installation package is available for RHEL, CentOS, Debian, Ubuntu, Suse and most of other supported Bacula Enterprise Linux distributions. If you want to use hardware or file-system provided deduplication, refer to the bacula Aligned Volumes Driver product whitepaper. Global Deduplication is performed by Bacula Software. The reason for this is, if your disk develops a bad block, instead of damaging one file (that may be stored many times), it may damage all (dozen, hundred) files that contain that same block of data.ĭeduplication is not implemented for tape devices. If you are not able to use ZFS, we advise you to use XFS. Normally 10GB is required from 1TB of backups.įor deduplication storage, prefer file systems that checksum everything such as ZFS and by using hardware RAID technology. #Em client deduplicator code#To do efficient and fast deduplication, the Storage Daemon will need additional CPU power (to compute hash codes and do compression), as well as additional RAM (for fast hash code lookups).įor effective performance, the deduplication Index should be stored on SSDs as the index will have many random accesses and many updates. #Em client deduplicator full#For example, Bacula features like copy/migrate and Virtual Full can be up to 1,000 times faster. Handling references instead of the data can speed up most of the processing inside the Storage Daemon. Deduplication works for backups but also when doing a restore. ![]() It works when the destination already has a copy of the original chunks. In the best cases, depending on the backed up data deduplicability, it may reduce the backup disk space needed by 99%.īacula Global and Storage Deduplication Plugin already compress data after deduplication, so you should avoid backing up compressed data, which usually renders a poor deduplication ratio.ĭeduplication can significantly reduce the network bandwidth required because both ends can exchange references instead of the actual data itself. ![]() Bacula Enterprise offers several ways to tackle these challenges, one of them being Global Endpoint Deduplication, which minimizes network transfer and Bacula Volume size using deduplication technology.ĭeduplication can significantly reduce the disk space needed to store your data. One of those challenges is the growing amount of data to be backed up, together with limited time to run backup jobs (backup window). IT organizations are constantly being challenged to deliver high-quality solutions with a reduced total cost of ownership. This Quick Guide provides the steps required to implement deduplication with Global and Storage Endpoint Deduplication backups and Bacula Enterprise Edition. ![]()
