Issues speed backup one client

Hello

Currently the server performs 4 backup tasks, 3 always work correctly, the problem is with one server. The problem is that it usually takes many hours to complete a backup.

There are days that it takes 3 or 4h, another day 6h, 18h, 19h, etc… the copied data is always about 10 GB only.

I bought a Change block tracking license to speed up the process, but nothing has changed.

URBACKUP SERVER
Windows server 2019
Urbackup 2.4.14

BACKUP
Windows server 2012 r2
Urbackup client 2.4.12-CBT

Today the copy started at 00:23 and it has not passed 0% and it is 9:29

Writer is in error state during snapshot creation. Writer data may not be consistent. This means the files open by this application (e.g. databases) will be backed up in a crash consistent state instead of a properly shutdown state. Properly written applications can recover from system crashes or power failures.

Maybe click on the show log button to see exactly what it does.
Then you’d need to check if the transfer is set to block hash in the advanced settings, otherwise CBT won’t work for the files.

Hi,

Change the option “Local incremental file backup transfer mode:” from “Hashed” to “Block difference - hashed” but I haven’t changed anything.

Are you sure there’s no I/O error with the client system?

Are there any generic Windows error messages in the EventViewer?

Hi BrainWaceCC

On this same server there are 2 different backups:

1.- Every day make a backup to a USB hard drive.
2.- Every week make a backup to an RDX unit.

In both cases without problems, in approximately 2 hours it performs the backup (differential).

Event Viewer, only found this:

Have you tried a different USB drive just to verify that it is not something about the drive or the port that the system is connected to?

-ASB

The USB disk, after performing the Backup, is automatically disconnected. It is only connected during the backup process so it does not interfere with Urbackup at any time.

This morning:

The backup starts at 00:00, at 9:27 the percentage bar in “progress” started to move. Currently (10:50) it stays at 98%…There are days when it takes about 3h/4h to finish the backup, on other occasions this happens…

UPDATE:
Backup completed, this is the log:

Are there any errors in the EventViewer logs for the UrBackup server and the UrBackup client?
