Troubleshooting Restore - Macintosh File System iDataAgentThe following section provides information on some of the troubleshooting scenarios related to restore:
|Some of the files included in the user-defined subclient are not restored.||You may be performing the restore of user-defined subclient along with the restore of default subclient.
When you are recovering data backed up by the default subclient, you cannot recover the data backed up by a user-defined subclient.
|Browse from default subclient displays No Backup at Time error||Ensure that you do not include the root directory (/) as the subclient content.
When performing point-in-time restore from the default subclient, include the data/folders under the root directory as the subclient content.
|Restore fails when trying to restore to a Unix FAT32 directory||You may be restoring the full contents of a Unix directory that contains more than 32,767 files to a single Unix FAT32 directory.
The number of entries in a single FAT32 directory cannot exceed 32,767.
|Error while loading shared libraries||On Linux clients, the below error appears when we run any process or service:
<process name>: error while loading shared libraries: <lib>.so: cannot enable executable stack as shared object requires: Permission denied
#./ifind -getmnt -all
As a workaround, do the following steps:
|ACLs are not restored||Sometimes, when you restore data to a NFS-mounted file system, ACLs and other extended attributes may not be restored.|
|Restore fails when trying to restore a running executable file.||Ensure that you are not including any running executable files in the restore operation.|
|Restore operation fails when special characters are included in the data|| Restore operations on files containing , /or the \ characters fail when restored without browsing. In order to restore these files using a browse operation, the directory that contains these files, or a higher level directory, must be selected in the browse window as content to restore.
For example, if there is a file with name filename in the /opt directory, then you must select the /opt directory or any directory that contains /opt for restore. If you select only the file, the restore will fail.
|Browse and Restore Failure||
In a disaster recovery scenario, use the following procedure to recover data associated with the following entities:
- Deleted storage policy
- Deleted client, agent, backup set or instance
Before You Begin
This procedure can be performed when the following are available:
- You have a Disaster Recovery Backup that contains information on the entity that you are trying to restore. For example, if you wish to recover a storage policy (and the data associated with the storage policy) that was accidentally deleted, you must have a copy of the disaster recovery backup that was performed before deleting the storage policy.
- Media containing the data you wish to recover is available and not overwritten.
- If a CommCell Migration license was available in the CommServe when the disaster recovery backup was performed, no additional licenses are required. If not, obtain the following licenses:
- IP Address Change license
- CommCell Migration license
See License Administration for more details.
- A standby computer, which is used temporarily to build a CommServe.
Recovering Deleted Data
- Locate the latest Disaster Recovery Backup that contains the information on the entity (storage policy, client, agent, backup set or instance) you are trying to restore.
- Check the Phase 1 destination for the DR Set or use Restore by Jobs for CommServe DR Data to restore the data.
- If the job was pruned and you know the media containing the Disaster Recovery Backup, you can move the media in the Overwrite Protect Media Pool. See Accessing Aged Data for more information. You can then restore the appropriate DR Set associated with the job as described in Restore by Jobs for CommServe DR Data.
- If the job is pruned and you do not know the media containing the Disaster Recovery Backup, you can do one of the following:
- If you regularly run and have copies of the Data on Media and Aging Forecast report, you can check them to see if the appropriate media is available.
- If you do not have an appropriate report, and know the media that contains the DR Backup, catalog the media using Media Explorer. Once the cataloging process is completed, details of the data available in the media are displayed.
- On a standby computer, install the CommServe software. For more information on installing the CommServe, see Install the CommServe.
- Restore the CommServe database using the CommServe Disaster Recovery Tool from the Disaster Recovery Backup described in Step 1. (See CommServe Disaster Recovery Tool for step-by-step instructions.)
- Verify and ensure that the NetApp Client Event Manager NetApp Communications Service (EvMgrS) is running.
- If you did not have a CommCell Migration license available in the CommServe when the disaster recovery backup was performed, apply the IP Address Change license and the CommCell Migration license on the standby CommServe. See Activate Licenses for step-by-step instructions.
- Export the data associated with the affected clients from the standby CommServe as described in Export Data from the Source CommCell.
When you start the Command Line Interface to capture data, use the name of the standby CommServe in the -commcell argument.
- Import the exported data to the main CommServe as described in Import Data on the Destination CommCell.
This brings back the entity in the CommServe database and the entity is visible in the CommCell Browser. (Press F5 to refresh the CommCell Browser if the entity is not displayed after a successful merge.)
- You can now browse and restore the data from the appropriate entity.
As a precaution, mark media (tape media) associated with the source CommCell as READ ONLY before performing a data recovery operation in the destination CommCell.
Macintosh operating system restore failed due to kernel panicDuring disaster recovery, when rebuilding the operating system, the computer does not restart correctly due to kernel panic. In such cases, refer Apple documentation to recover the system from kernel panic and resume the disaster recovery operation.
CC0009: Users have access to files and folders belonging to others users
Users are able to Browse, Find and Restore files and folders associated with other users from all user-interfaces such as the CommCell Console, Web Console, etc.
- ACLs (Access Control Lists) are not included in the backup, and/or
- The user has Browse capability instead of only the End User Access capability.
- Make sure that only End User Access capability is configured on the client computer. For instructions, see Configuring End-User Operations on Client Computers.
Specifically ensure that Browse capability is not assigned to these users.
Assigning End User Access capability helps to maintain multiple user profiles on the same laptop (or desktop) and ensures that each user has the ability to browse and restore only the data to which he or she has access.
- Make sure that the Catalog ACL (end user access control list) option is enabled in the subclients before performing a backup as described in:
- Subclient level - Enabling End User Access Control During Backups
- Subclient Policy level - Enabling End User Access Control During Backups.
This option can be enabled only for users who log in with their Active Directory credentials.
Once enabled, this option ensures that ACL s are included in the backup, which in turn, allows users to access only those files and folders for which they have permissions.
After enabling this option, make sure to run a Full backup subsequently. This will ensure that ACLs are available in the backup data.
Conversely, if you run a Differential or Incremental backup after enabling this option, only the newer data will include ACLs.
