Restoring data from a backup

1 Restoring data from a backup The following topics explain how to find a backup to restore and then perform a restore: Finding a backup to restore on page 98 Restoring to the original location on page 101 Restoring to a different location on page 102 Restoring to multiple locations on page 105 The options for the restore destination depend on the plug-in type. For example, the SQL Server plug-in enables you to restore to a file instead of to SQL Server, and you cannot restore to multiple locations with the Oracle plug-in. The user guide for each plug-in provides details on the available options and how to perform each available type of restore. Finding a backup to restore You can find Avamar client backups for a restore either by date or by files and folders. Some plug-ins, content, or restore types use only one method to locate backups. The guide for each plug-in provides details on which methods are available. Avamar generally supports the use of specific supported international characters in directory, folder, and filenames. However, proper display of international language characters is contingent on the client computer s Java locale and installed system fonts being compatible with the original language. If you browse backups that were created with international characters and a compatible font is not installed, then any characters that cannot be resolved by the system appear as rectangles. This is a normal limitation of that particular situation and does not affect the ability to restore these directories, folders, or files. The EMC Avamar Release Notes provide additional international language support information. The following topics provide details on finding a backup for a restore: When to find a backup by date on page 99 How to find a backup by date on page 99 When to find a backup by file or folder on page 100 How to find a backup by file or folder on page EMC Avamar 7.0 Administration Guide

2 When to find a backup by date Locate backups by date when: All data that the client backs up, such as databases, storage groups, or volumes, is backed up in a single backup set. The exact path or name of the file, folder, or database you want to restore is unknown. The content from a backup you want to restore is before a specific date or event. For example, you know approximately when a file or folder was lost or corrupted, and need to find the last backup before that date. The specific types of backups are known. For example, you run scheduled disaster recovery backups every Wednesday and Saturday night, and you run full volume backups daily. If you need to rebuild a server, you can select the disaster recovery backup with the date closest to the event that caused the loss of data. How to find a backup by date To find backups for a restore by date: 1. In Avamar Administrator, click the Backup & Restore launcher button. The Backup, Restore and Manage window appears. 2. Click the Restore tab. 3. In the clients tree, select the client. You cannot view clients outside the domain for the login account. To view all clients, log in to the root domain. 4. Click the By Date tab. 5. Select a backup from the calendar: a. Use the year and month navigational arrows to browse to a backup. Dates highlighted by yellow indicate a valid backup was performed on that date. b. Click a date highlighted by yellow. A list of backups that were performed on that date appears in the Backups table next to the calendar. Restoring data from a backup 99

If you browse the client file system, specify a valid client username and password, then click OK. The username and password must have read permissions on the files and directories that you select for restore. 9. Select Actions > Restore Now. Locate backups by the specific files or folders contained within each backup when: Data that the client backs up, such as databases, storage groups, or volumes, is backed up in separate backup sets. For example, you know that \\Server_Name\Databases\Database_1 is backed up in one backup set and \\Server_Name\Databases\Database_2 is backed up in another backup set. If you know the content you need is in Database_2, or is the entire Database_2 database, then you can specify the path or browse to the Database_2 folder. You want to see multiple versions of the same file. The date of the backup or what was saved in a backup is unknown, but you know the name of the file or folder. How to find a backup by file or folder To find a backup by specific files or folders in that backup: 1. In Avamar Administrator, click the Backup & Restore launcher button. The Backup, Restore and Manage window appears. 2. Click the Restore tab. 100 EMC Avamar 7.0 Administration Guide
