Choose the time and day of the month the backup should run. Vembu will run the backup every month on the particular day and time chosen. Vembu will run at the stipulated time/day only.
Step 5: Additional Full Backup
Typically, you would do a full backup first time you backup your data and thereafter only do incremental backups. However, like in a typical enterprise scenario, if you want to run full backups periodically and run the incremental backups in between two full backups you can Configure Additional Full Backup (Additional full backup schedule is mandatory to keep the incremental limited. Please configure an additional full backup for this schedule).
For 'Run Every Few Hours/Run Daily' incremental backups, the Additional Full Backup settings will allow you to configure daily/weekly/monthly additional full backups. For weekly and monthly backups, only Monthly additional full backups are possible.
Additionally you can specify the maximum number of full backups that need to be stored in the server. For example if you configured a weekly backup and additionally if you configure a monthly full backup, then Vembu OnlineBackup will take a full backup first time and then weekly do an incremental backup. The next month, Vembu OnlineBackup will do a new full backup and subsequently run the weekly incremental backup over this full backup. After 6 months you will have 6 separate full backups in the Vembu Cloud along with weekly
incremental versions under each of the 6 full backups. If you have configured to store only 6 full backups "Store maximum of 6 full backups" here. On the 7th month, Vembu OnlineBackup, after finishing the 7th full backup, will delete the first full backup along with its weekly incremental backups thus retaining always the last 6 month backups.
Note:
The Default full-backup to store is 2Advanced Options

Advanced Backup Schedule Settings
There are three options here on how the backup should be scheduled.
1. Runthis backup each time Vembu OnlineBackup restarts – If you enable this option by checking the check box, then this backup schedule will be run every time Vembu
OnlineBackup is restarted or the machine is rebooted irrespective of the actual schedule time of this backup schedule. This is to ensure that any modified or new files created when Vembu OnlineBackup was down are backed up as soon as possible. In case of the Continuous backup or ‘Run every…’ scheduling options, backups will run each time Vembu OnlineBackup restarts – by default.
2. Run this backup immediately after saving this configuration (thereafter, Backups will be scheduled as per the schedule stipulated) - If you enable this option, then this backup schedule will be executed once immediately after you save this backup schedule – even if it's not yet ‘time’ as per the schedule. For example if you configure a daily backup at 10.00 AM but you configured the backup at 8.00 AM, then the backup schedule will be run once immediately (8.00 AM) and then as per schedule (e.g. daily at 10.00 AM). 3. Attempt to run this backup every 5 minutes in case of non-completion because of a problem
(Network error etc.) - If enabled, the user can choose to reschedule this backup every 5/10/15/20/25/30 minutes, whenever an attempted backup is incomplete because of a network error, server crash etc. The number of times the backup will be rescheduled (due to an error) can be configured to be in between 1-5 or unlimited, with the default setting as 5. This is to ensure that an incomplete backup is completed as soon as possible without waiting for the next actual schedule time. Note that this option is enabled by default.
Pre & Post Backup Commands (Optional)
This feature provides the ability to configure running custom actions before and after executing a backup schedule. The custom actions may include running an application or some script files.
Vembu OnlineBackup | Admin User Guide | VMware Backup and Restore 91
When is this feature useful?
If an application has exclusively locked a file and you need to close the application before Vembu OnlineBackup can backup that file, then you can run a Pre-backup command to close the application and then a post-backup command to open the application again after Vembu OnlineBackup successfully backs up the file.
How does this feature work?
Whenever a backup schedule starts, Vembu OnlineBackup will start the Pre Backup commands and wait till the timeout value. After completing the Pre Backup commands, Vembu
OnlineBackup will transfer the configured files & folders to the Vembu Cloud. After transferring the configured files and folders, Vembu OnlineBackup will run the Post Backup Commands. If multiple servers are configured for the backup schedule, then both the Pre and Post Backup commands will run while backing up to each of the servers.
Pre & Post Backup command settings:
You can provide maximum of 5 Pre Backup commands and maximum of 5 Post Backup commands for each backup schedule. Both the Pre and Post Backup commands are optional.
1. Command Name: This filed is mandatory. This is the command that should be run. The command should be provided with full path. If the command name is in the system command path, then providing full path for the command is not necessary. The command can be an executable file such as application exe, batch files, script files etc. Example: C:\MyTools\myzip.exe. A simple zip tool which compresses the given files or folders.
2. Arguments: You can provide any command line arguments for the command to be executed.
Example: For the Command C:\MyTools\myzip.exe, the arguments may be 'High Zip Replace "D:\Project" myproject.zip' [without quotes]. Here, the High may denote high compression, Zip denotes zip file format, Replace denotes replacing existing files, 'D:\Project' denotes folder to compress and 'myproject.zip' denotes the target compressed file name.
3. Working Path: This field specifies the directory path from which the Command has to be run. If this field is left empty, then the command will be executed from the Vembu OnlineBackup working path [Vembu OnlineBackup Home]
Vembu OnlineBackup | Admin User Guide | VMware Backup and Restore 92 4. Timeout: This filed is used to specify a timeout value, in seconds, for the command to
finish execution. Vembu OnlineBackup will wait for so many seconds for the Pre and post command to finish running. If the command still runs beyond the timeout period, then Vembu OnlineBackup will abruptly terminate the command and will continue with the backup schedule.
Please note that if you provide -1 value, then the command will run till completion and Vembu OnlineBackup will wait till the command completes. If command never
completes, then Vembu OnlineBackup may just infinitely wait without proceeding with the backup schedule.
Example: 60. For the myzip.exe command, the myzip.exe command will compress the given project folder up to 60 seconds. If the myzip.exe completes before the timeout period, say 15 seconds, then Vembu OnlineBackup will immediately continue the next Pre Backup Command [if configured] or continue with the backup schedule.
So, the example command will look like below: Command Name : C:\MyTools\myzip.exe Arguments: High Zip Replace
Working Path : D:\Project Time out : 60
The whole command will be run up to 60 seconds as below: C:\MyTools\myzip.exe High Zip Replace "D:\Project"
Application Aware Options
Application aware process is to create consistent database snapshots by quiescing the applications using Microsoft VSS API.

Troubleshooting Tips
Error: “Error While Connecting to the VMware Server 'server Name'. Invalid Login
Credentials.”
Cause: This error is shown if the user name or the password for the VMware Server is
wrong.
Solution: Go to the page 'Backup -> Add VMware Backup -> Add VMware Servers' and edit the credential of the selected VMware Server and save.
Error: “Error while connecting the VMware Server 'server Name'. Reason: Please check
VMware Server configuration settings and also check the VMware server is up.”
Cause: This error is shown if unable to connect to the selected VMware Server/VCenter
or the VMware Services are not started in the VMware Servers/VCenter Solution: Check if the selected VMware Server is up and is accepting connections Check if all the Services of VMware are started in the selected VMware Server
Vembu OnlineBackup | Admin User Guide | VMware Backup and Restore 94 Check the network/firewall settings in the client machine and make sure Vembu OnlineBackup is able to access the VMware machine.
Error: “Error While connecting to the VMware Server 'server Name'. Reason: Unable to
connect to the host.”
Cause: This error will occur when Vembu OnlineBackup is not able to connect to the
selected VMware Server as the VMware services are not started. Solution: Please start all the VMware Services and then try again.
Error: “The virtual machine cannot be found.”
Cause: This error occurs if the configuration files of the virtual machine are not available or corrupted.
Solution: Please Check the VMware Configuration files *.vmx and *.vmdk available in the OS VMFS file system. You can check this by powering on the particular Guest OS from vSphere Client console - this will give the exact error details of the issue.
Error: “Error While Getting VMware Login Details Reason: The User Name or Password
is empty. Please check the added VMware Server 'VMware Server' is Edited/Deleted”
Cause: This error will be reported, if the name of the added VMware Server is changed
or the VMware Server is deleted from the 'Added VMware Server's List.
Solution: a. If the added VMware Server/VCenter is deleted, add the VMware
Server/VCenter again in 'Add VMware Server's page and schedule again.
b. If you have changed the credentials to the added VMware Servers/VCenter, then edit the already added VMware Servers/VCenter from the 'Add VMware Server's' page and provide the credential again.
