UrBackup Server 1.3.2-1.exe 2014-01-20
concurrent clients at the same time -5 - all Windows XP with Gigabit Ports
Client versions 1.3 stable
Backup storage path: another 2012 R2 Server \servername\share1$
Image Backup is so slow - only 100Mbit is saturated with 5 client - but i have a 1000Mbit connetion
If i start a filecopy from backup storage path to the urbackup server- the gigabit network link is saturated - over 100 MB / sec - but Urbackup uses only max 10 MB per sec.
I have not limited the network speed in urbackup
Speed goes up for a single client if i check “Temporary files as image backup buffer:” but also limited to 100 Mbit aka 10 MB /sec
PS
Urbackup looks much more stable with the new WIP Version(UrBackup Server 1.3.2-1.exe) - no disconneting Clients now - which often occurs with the “stable” version 3.2.1 on Server 2012 R2
hy - i think the bottlneck is urbackup - if one client is able to create 10 Megabytes per second with a 2012 R2 server and a temp directory - i think 5 clients should be at minimum 2-5 times faster - but this is not the case. I’am stuck at arround 7-to 10 Megabytes per second for combined traffic of all clients. The CPU Usage is arround 40 to 50 % in urbackup server - 30 % only for urbackup_srv.exe and about 6-8 % for System interrupts.
I disabled the temp directory - because i dont have enough space on the server.
In the past i upgraded the old installation without uninstalling the previous version .
Now i uninstalled the WIP version -and installed the old stable one - but i don’t be sure which files must be backed up to reinstall the server -
i saved
backup_server.db
backup_server.db-shm
backup_server.db-wal
backup_server_init.sql
backup_server_settings.db-shm
backup_server_settings.db-wal
server_ident.key
server_token.key
and after a new install -i disabled the service “Urbackup Windows Server” and copied these file into the folder
C:\Program Files\UrBackupServer\urbackup
Is that correct to correctly reinstall the server ?
Because the server is virtual - i added now 2 extra cores and disabled dynamic memory - cpu usage is now 22 % - but i can’t get above 100 Mbps (10Megabytes per/second)
result of all these changes - nothing - the performance is very limited - i can’t figure out the bottleneck
Now i have 5 clients reached 100 % in the progress bar in the server activity window - but now the Network Perfomance drops again from gigabit to 100 mbit ! (i think urbackup is copying the files from temp to the final destination)
