To be a successful server backup adopter, you can't do it alone. You have to have a comprehensive, educational and robust onboarding process, in which you can learn how best to use backup software. Are you currently receiving this level of support from your vendor?
If you're just getting started with R1Soft's Server Backup Manager (SBM), we want you to believe that we've got your back every step of the way. One of the ways we strive to convey this is through our extensive documentation on the company's public wiki. Did you know you have all of these resources available to you? To make it even easier for you, in this new partner success blog series, we're highlighting the links and passages hosting providers need to know to effectively implement our tool.
In this second post, we continue the first round with Part 2 of SBM key terms and definitions.
Limit Disk Space Available to Server Backup Manager
Limited disk space available to SBM is an option that defines how much free space is left available for use by Server Backup Manager. This is an effective limit defined in percent of the device volume. When the system reaches the set limit, you cannot generate any new recovery points. As a result, any replication stops and fails.
Locking Recovery Points
Server Backup Manager allows you to lock recovery points and protect them from a merge or deletion. note that when a recovery point is locked, SBM cannot perform the Disk Safe verification task. For more information about this task, see Schedule Disk Safe verification.
A log file is a file that lists actions as they occur. Server Backup Manager includes log files that contain messages from tasks performed by the Backup Agent (cdp.log), log files that contain messages from the Backup Manager (server.log), and log files that contain messages from the Web GUI and start up/shut down tasks (monitor.log). For more information about log files, see Access log files.
As a security precaution, Backup Agent allows connections only from specified Backup Managers. To specify a Backup Manager, add a manager public key to the Backup Agent by creating the appropriate text file on the server. For more information about encryption keys, see Add key to Linux Backup Agent and Add key to Windows Backup Agent.
Merge Recovery Points
When you delete a recovery point you are actually merging the unwanted recovery point and closest existing recovery point. You can discard deltas between the two recovery points and free the space the data consumes in the Disk Safe. For more information about recovery points, see Merge recovery points.
In Unix-like systems, a mount point is the location in the operating system directory structure where a mounted file system appears. In Microsoft Windows, mapping a drive is the equivalent to a mount point.
MySQL is database software that features a variety of tools and provides multi-user access to a number of databases. Server Backup Manager allows you to back up and restore MySQL databases. For more information about SBM and MySQL, see Protect MySQL.
Partition as an action means to divide memory or mass storage into isolated sections within the hard disk. A partition table is a placeholder for the description of a partition on the hard disk.
Policy frequency is the recurrence selected for running the policy. You can select the policy to run:
- On demand
- By the minute or hour
- Daily, weekly, monthly, or yearly
For more information about using policies, see Manage policies.
A recovery point is a set of many deltas that represent the state of a disk volume block at a particular point in time. Each delta is available for use by one or more recovery points. The Disk Safe maintains the relationship between deltas and recovery points. For more information about recovery points, see Manage recovery points.
Recovery Point Limit or Retention
Recovery point limit or retention defines how many recovery points you want to keep in the Disk Safe. Note that the system merges old recovery points. For more information about recovery points, see Manage recovery points.
Replication is the operation of copying block-level deltas from the server to Server Backup Manager into a new recovery point. Each replication creates a point-in-time image or recovery point of the device. For more information about replication stages, see Understand the replication stages.
Servers are computers that are backed up or replicated. Server Backup allows you to manage backups for multiple servers. For more information about servers, see Manage servers.
Snapshot the Disk or Volume
The first stage of replication is to create a snapshot of the disk or volume. The system creates a point-in-time snapshot of the server file system for a consistent, open file backup.
Synchronization is the process of creating the Disk Safe point-in-time snapshot and computing deltas based on the last completed synchronization. For more information about synchronization, see Manage policies.
Vacuuming Disk Safes
Vacuuming a Disk Safe is the process of reducing the on-disk size by "vacuuming" or removing blocks that are no longer used by a file system. For more information about vacuuming, see Vacuum Disk Safes.
Virtual Hard Disk (VHD) is a file format used as a hard disk of a virtual machine. VHD allows you to deploy multiple operating systems on a single host machine. VHDs are available with software that enables you to evaluate different software solutions in your own environment without the need for dedicated servers or complex installations. The Hyper-V VHD Explorer allows you to manage all your mounted VHD files. For more information about Hyper-V VHD Explorer, see the product page on the R1Soft Website at www.r1soft.com.
Warn When Disk Usage Exceeds
Warn when disk usage exceeds is a warning level where users are informed that they are close to reaching their effective limit. The level is also defined in percent of the device volume. This limit is usually a lesser value to the Limit disk space available to Server Backup Manager option.
