LuckyBackup is soooo slow to Sync

Actually I am being a bit facetious.

It takes Far Longer for the extUSB drive to lock into NEMO than the Sync operation does.

Ha., was doing some Googling this afternoon to find out why LB is running super slow on my setup and saw your post. My backup server is running LMDE4 and my main server pure Debian 11.x. I've been using Lucky Backup for a couple of years to rsync from my main server to the backup one on a daily basis and something is out of whack. I'm transferring LOTS (hundreds and hundreds) of 350 meg files and the backup started today at 9am and 6 hours later, only about 248 gigs of files were copied over. I checked LB and the transfer rate was around 1-2Mbps, if that.

I don't know what's to blame. I don't think LB/rsync likes backing up hundreds of gigs of 'small' files. The transfer seems to run plenty fast when copying over 5 and 10 gig files but these smaller ones make things run like molasses.

Check the health of your source and destination drives but also make sure the SATA data and power cables are okay too (not noticeably loose connection wise or stiff and brittle through degradation in the the case of older cables)
I’ll tell you a DNS joke but be advised, it could take up to 24 hours for everyone to get it.

I figured out what the problem was. It was because I was using an NFS share. I guess rsync (especially when backing up a LOT of small'ish files) can be quite slow when backing up to an NFS drive. I tried all the command line switches I could think of and nothing worked.

I switched the share to SMB and backup speeds are WAY faster now.
