Linux and Synthetic Backups
I'm trying to get a weekly synthetic full backup of my Linux servers going with Backup Exec 2010 (Media server is Windows 2008). I've installed the Linux agent and am able to run regular full, incremental & differential backups from the Linux host. When I create a synthetic backup policy (a copy of the example template generated by Backup Exec) I can run the baseline full backup without any trouble but the incremental backup fails - actually crashes the remote agent is more accruate. The job runs for about 10 minutes and then fails when the remote agent crashes. During its run the data transfer rate is only about 200MB/min while a normal job (without the synthetic option checked) achieves about 1GB/min. The error logged is:
Completed status: Failed
Obviously the above error is simply because the agent has crashed and communication fails. On the console of the Linux server I see:
*** glibc detected *** free(): invalid next size (fast): 0x08234948 ***
I've found that if I uncheck the "Collect additional information for synthetic backup and for true image restore" flag in the incremental job template then the backup runs just fine. Has anyone else seen this problem? The Linux agent is running on Debian 4 & 5 systems. There are a few servers that have completed the incremental job with the synthetic option enabled one night, as scheduled, but then failed the next night. I know Debian isn't officially supported but am hoping that someone out there has got it working.
I still have to investigate further, i.e. wade through the 22MB log file generated, I will post more info as I acquire it but if anyone out there has any suggestions, any help would be appreciated.
