Viewing backup information
Backups are organized in a hierarchical order on the DS-System with the following structure
• DS-Systems contain customer accounts
• Customer accounts contain DS-Client accounts
• DS-Client accounts contain backups.
For backups on the DS-System, you can view information about backed up files, including generations of the same file and storage options.
To view backup information:
1. On the Customers tab, right-click the backup for which you want to view the information, and then select one of the following options:
• Fast Browse – This option omits the statistics for large folders. The information is cached until you refresh or restart the service.
• Browse – This option displays folder information, file information, and storage statistics.
2. Right-click the folder containing the files you want to view, and then click Show Files.
3. For additional information on the file, right-click the file, and then click Storage info. The Storage Info dialog box displays the following information:
Table 1 Storage information details
Column | Description |
|---|
Gen | Corresponding file generation. |
Backup Time | Time stamp when the file was backed up. |
Last Modified | Time stamp when the file was last edited. |
File Type | DS-System online file type for the file that was backed up. |
Link ID | • Master/Delta – If value is zero, there are no dependent generations. Any value other than zero, is the generation ID of the next generation in the delta chain. • Library File – ID of the DS-Library file. |
Flags | Backup option that has been applied to a particular file. P – Permissions S – Backup Streams G – Digital Signature M – Master File D – Delta E – Extended Attributes (Netware) B – Bindery (Netware) N – NDS (Netware) R – Registry (Windows) X – POSIX |
Attr | Attribute of the backed up file. The options are: R – Read Only H – Hidden S – System A – Archive C – Compressed D – Directory |
Size | Original size of the file. |
DS Size | Actual size of the file as stored on the DS-System. |
Stream Size | Full transmission size of the file, including file security, permissions, streams, etc. |
Encryption | Type of encryption used for the file. |
Compression | Type of compression used for the file. |
Archive ID | Archive package number for the generation. |
Archive Time | Time when the corresponding generation was pushed to BLM Archiver from the online storage. If there is data in this field, it means that this generation has been archived, and can be restored only from a BLM restorable image. |
4. To verify the link information for a specific generation of a file, which confirms the DS-System can find the required components for the backup generation, select the file, and then click Verify Link.
• For Delta generations, this verifies the links to required data blocks in previous generations (back to the master).
• For Master and Regular files, this verifies the link to the source file.
• For Library files, this verifies the link to the source library file.
5. To optimize a master generation of a file by reducing the storage space it occupies, select the master generation, and then click Optimize. If the preceding generation is also a master, the DS-System converts it to a delta that depends on it.
NOTE: To optimize a backup, right-click the backup, and then select Run Master/Delta Optimize. By default, the DS-System optimizes the master files of the backup at the block-level and converts back-to-back masters into the master-delta chain. Additional optimization depends on the
FixDeltaChain advanced configuration parameter. For more information, see
“Configuring the advanced settings”.
6. To restore a specific backed up generation of a file, select the file, click Restore, and then do the following:
a) In the Private Key Type box, select the encryption type. In the Private Key box, type the DS-Client private encryption key.
b) In the Account Key Type box, select the encryption type. In the Account Key box, type the customer account encryption key.
c) In the Restore Reason box, select the reason for the restore request.
d) Click Restore.
e) In the Save as window, select the destination for the restored file.
NOTE: Only one generation can be restored at a time. When attempting to restore a generation from a backup with multiple files and inter-dependent components, the restored files might not be usable. Even if you restore all the component files, you would require the DS-Client to resolve them to the original backup state. If the file is backed up with File Permissions / ACL (“P” flag) or Streams (“S” flag), those permissions or streams are not restored.
7. To refresh the list of files, click Refresh.
8. Click Close.
