 @nagendra said in Problem accessing ZCS upstream server. Cannot connect to the ZCS upstream server. Connection is refused.: @scottalanmiller you mean size ?? its around 2 GB every hour. it worked for almost 1 day but next day this issue started .. nvm i will start backup every nite or every 6 hrs That's not very much. That should take no time at all. Any idea why it is so slow? 
- 
 @nagendra Okay but what backup are you using? 2 GB per hour is not that bad what we might need to know is the underlying storage and hardware.

And what tool are you using for the backups? Veeam Endpoint? R&R?

 @scottalanmiller am using shell script for backup...

 @nagendra Okay are you using any of this? 
 https://github.com/lucascbeyeler/zmbackup
 https://wiki.zimbra.com/wiki/Open_Source_Edition_Backup_ProcedureI use the first link with a slightly modified backup of the mailboxes deleted items since the hot backup doesn't backup those folders (This is the opensource version). 
- 
 @dbeato ohh thanks for the tools i will give a try.. 
- 
 If this is a VM server you can also use LVM for snapshots. 
- 
 @dbeato yes its VM .. LVM Snapshot ?? i have option but havent tried it... can we scheduled the backup 
- 
 @nagendra LVM Snapshot are what Volume Shadow Copies are for Windows in Linux. Did you setup your Linux server with an LVM volume? 
- 
 @dbeato yes  
- 
 @nagendra Take a look at 
 https://wiki.ubuntu.com/Lvm
 https://wiki.zimbra.com/wiki/Open_Source_Edition_Backup_Procedure
 They both provide LVM backups examples

 Is a snap going to be better than a direct grab in this case? File grab, compress, send... might be the simplest thing. 
- 
 @reid-cooper Yeah, there are couple of options
