Exchange 2007 CCR - Transaction Logs were not truncated (only copy backup)

Hi

One day Exchange 2007 transaction log stopped being truncated. The backup job status is 0 - data is backed up successfully.
In bpkar log there is strange message

17:28:42.539: [3388.2972] <2> tar_base::backup_finish: TAR - backup: elapsed time: 8135 secs 51578267 bps

17:30:43.559: [3388.2972] <4> dos_backup::tfs_reset: INF - Snapshot deletion start

There is no logs in vnetd and bpcd at 17:30

As a result we have only "copy backup" instead of "full backup" and we have to manually truncate Exchange logs.

Any ideas?

Hi

Logs are not truncated while backing up to tape. When I do a backup to a disk, exchange logs are trancated. All backup jobs are performed using the same backup policy.

Do you have any idea?

Here is a resolution.

In my case the problem was at the Local Area Network layer.
Routers ware closing TCP/IP sessions after few seconds after the first FIN flag was sent.
