I am doing a full backup using PgBackRest from a production server to Reposerver.
My connection is IPSec VPN over ILL ( 8 Mbps link) between the Production DB Server and the remote RepoServer.
I understood the bottleneck of 8 Mbps between servers. (Server NICs 10Gbps and switch)
Query : I have started the backup command and it is running (may go for hours and days as link speed is minimal) .
If the link disconnected or Network error happens before completion of the backup command Definitely the option is to reissue the backup command again.
If so, does the backup process start again from scratch ? or it resumes from where the backup process is stopped ?
If it starts from scratch I am afraid that I can''t complete the initial full backup never :(
Or is there a work around if the network connectivity is lost in between ?
Any suggestions much appreciated
Thank you ,
Krishane
