When transferring lots of small files in many folders with rsync, it tends to stay around ir-chk=1000/xxxxx, where xxxxx keeps counting up as it discovers new files, and the amount to check stays around 1000 until its on its last few folders.
How can I have it check for the entire file count before copying?
The command I was using to copy was:
rsync -av --progress source dest
384
Method 1: Using –progress option to see the rsync progress:Use the “–progress” in the rsync command and “-av” to get a summary at the end of file transfer, consisting of transfer rate, sent/receive bytes, speed of transfer, and total file size.
Rsync with --ignore-existing-files: We can also skip the already existing files on the destination. This can generally be used when we are performing backups using the –link-dest option, while continuing a backup run that got interrupted. So any files that do not exist on the destination will be copied over.
Determining which files to send By default, rsync determines which files differ between the sending and receiving systems by checking the modification time and size of each file. If time or size is different between the systems, it transfers the file from the sending to the receiving system.
by Shehroz Azam. Rsync is a very popular command used in Linux for syncing files or directories either locally or remotely. The reason behind its popularity is that it only takes the changes and copies them to the destination. Mostly, this command is used in keeping the data backup and restoration.
When transferring large amounts of data it is recommended to run the rsync command inside a screen session or to use the -P option: rsync -a -P remote_user@remote_host_or_ip:/opt/media/ /opt/media/ Exclude Files and Directories There are two options to exclude files and directories.
The problem is that rsync takes quite a long time (10-20m) before starting to move any files, I guess because it has to compute file lists for a very large number of small files. During this period, the newtwork utilization sits at a low 200-500KB/s, while when transferring files the speed is about 40MB/s.
Rsync is a fast and versatile command line utility that synchronizes files and folders between two locations over a remote shell, or from/to a remote Rsync daemon.
During this period, the newtwork utilization sits at a low 200-500KB/s, while when transferring files the speed is about 40MB/s. It usually happens that rsync takes about 15m to finally find something it has to copy, then takes 5 seconds to copy it, then continues checking for some other files to copy for another 5 minutes.
rsync -av --progress --dry-run --stats source dest
--dry-run doesn't transfer any files but will show how many bytes will be transferred.--stats shows a summary.a sample output:
