arcserve Backup Version   Applicable to all versions of arcserve Backup
arcserve Backup Task   Backup Operation, Restore Operation

Description:


Restore by Backup Media-Lets you restore a complete backup session from a specified media in a storage device. All files in the session are restored to the destination, unless filters are added to the restore job. Use this method when media was created by a different version of CA ARCserve Backup or if the database does not recognize it.

  • You can try this option for 1 session at a time only.
  • You can restore only files but not databases using this option.
  • You need to apply a filter else it will try to restore everything on the tape.
  • This option is not useful when sequence 1 media is missing or erased.

Important! If you cannot view the items that you would like to restore, the corresponding records may have been pruned from your database or they may be filtered. Please refer to the document  Unable to view sessions which explains how to fix such issues.

Use this option only when both catalog merge and sequential merge fail to generate catalog in a newer version of ARCserve  for the backup sessions for done using older versions of ARCserve .

Ex- if you fail to merge a CA Brightstore 11.5 media in CA ARCserve 16.


Usage of  Filters

You can include or exclude files based on the following criteria:

 

Specific file names, patterns, attributes, and size.

 

Specific directory names or patterns.

 

Files accessed, modified, and created before, after, between, or within a specific date range.

 

CA ARCserve Backup uses wildcards or substitute characters, except when it detects that an absolute path is specified. If a valid absolute path is specified, CA ARCserve Backup will only exclude (or include) the absolute path specified, rather than excluding (or including) more directories, as it would for regular expression.

The wildcard characters supported for job filters based on file name or directory name are as follows:

 

"*" --Use the asterisk to substitute zero or more characters in a file or directory name.

 

"?" --Use the question mark to substitute a single character in a file or directory name.

 

Important! Exercise caution when specifying filters for your backup or restore operation. Incorrectly applied filters may not  restore the data you need, and can result in lost data and wasted time.

Examples: Back Up Data Using Wildcards

The following table describes examples of how you can use wildcards in conjunction with filters to restore data.

Note: The following examples assume that the source data resides in drive C:\. 

Filter

Type and Criteria

Results

 

File

Include *.doc

CA ARCserve Backup restores all files residing in drive C:\ that contain a .doc file extension.

 

File

Exclude *.doc

CA ARCserve Backup restores all files residing in drive C:\ that do not contain a .doc file extension.

 

File

Include ?.doc

CA ARCserve Backup restores files that contain a single character file name and a .doc file extension. For example, a.doc, b.doc, 1.doc, 2.doc, and so on.

 

File

Include

C:\myFolder\CA*.exe and Include C:\test\ms*.dll

CA ARCserve Backup restores all of the following files:

 

Files residing in C:\myFolder that start with CA and contain an .exe file extension.

 

Files residing in C:\test that start with ms and contain a .dll file extension.

 

File

Exclude/Include

C:\DOC\C*

CA ARCserve Backup restores all the files backed up in the 'C:\DOC\' folder except the files starting with 'C.'

Directory

Include m*t

CA ARCserve Backup restores all directories residing in drive C:\ with directory names that start with m and end with t.

Directory

Exclude win*

CA ARCserve Backup restores all directories residing in drive C:\ except directories that start with win.

Directory

Exclude C:\test\m* and Include C:\test\media\*.gif

CA ARCserve Backup does not restore data.

In this example, the exclude filter criteria directs CA ARCserve Backup to exclude all directories that reside in C:\test that start with m. As such, C:\test\media is excluded from the backup. Although the include filter directs CA ARCserve Backup to restore all files that reside in C:\test\media and contain a .gif file extension, CA ARCserve Backup will not restore any files because C:\test\media is excluded from the backup.

Note: When you combine include filters with exclude filters, CA ARCserve Backup filters data based on exclude criteria first, and then by include criteria.

 Filter Options
You can access the filter options from the Backup Manager, Restore Manager, Copy, Count, Scan, Compare, and Purge Utility windows.


■ Exclude filters--Exclusions always take precedence over inclusions. For example, if you add a filter to include files that have an .exe extension, and you add another filter to exclude your \SYSTEM directory, all .exe files in the \SYSTEM directory are excluded.


■ Include filters--Results contain only those files that satisfy the filter specifications. For example, suppose you selected a session to restore your entire local hard drive, and you then set up a filter to include files in the \SYSTEM directory. The result would be that CA ARCserve Backup would only back up files from your \SYSTEM directory. No other files would be backed up.

More information:

Catalog Merge:

CA ARCserve Backup uses catalog files to record session details for sessions during backup. Under a standard configuration of CA ARCserve Backup 'DonotUseCatalogMerge' would not be present. If the key does exist  we need  to set its value to  0 (Default value) for catalog merge.

Sequential merge:

This would be used in cases where there is a problem with the normal merge operation as it relates to a specific catalog file, and as a result it will build a new catalog file by scanning the session file by file.

The following key needs to be created along with the dword

32 bit servers:

HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\CA ARCserve Backup\Base\Task\Merge

64 bit servers:

HKEY_LOCAL_MACHINE\SOFTWARE\wow6432node\ComputerAssociates\CA ARCserve Backup\Base\Task\Merge

DWORD: DonotUseCatalogMerge  Value = 1

Note: We need to  restart Ca ARCserve  services  after making the above change
