The following section provides information on some of the troubleshooting scenarios related to restore:
Restore Failures
|
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. |
Troubleshoot Performance Issues
If you are experiencing performance issues during restore, you can troubleshoot them by enabling logging of performance details in the log files on the access node and the IBM i Agent client. These performance counters contain information that help in resolving the performance related issues during restores.
IBM i Agent Client Performance Counters
The performance counters printed in the IBM i Agent client log files include:
|
File Write |
Disk data write for IFS file system. |
|
QanePipe Write |
Disk data write for QSYS library. |
|
Data Receive |
Network transfer speed. |
|
QaneCall |
Time spent in Qane call. |
|
Header Receive |
Wait time for next file header. |
|
mkParent |
Time spent to check and create parent folders. |
|
Set file attr |
Time spent while setting file attributes. |
|
Set file ext.attr |
Time spent while setting advanced file attributes. |
|
Thread Wait |
Time spent on waiting a Qane thread completion. |
Access Node Performance Counters
The performance counters printed in the access node log files include:
|
FileRead |
Average time spent in system call to read the file. |
|
CheckFileHole |
Average time spent to verify if buffer read from the disk is a hole. |
|
Close File |
Average time spent in system call to close the file. |
|
AllocBuffer |
Average time spent waiting for the network buffer. |
|
WriteBuffer |
Average time spent in sending the network buffer to the network. |
|
Disk Read |
Average speed of reading from the disk. |
|
Write |
Average speed of writing to the network. |
