Historically, 2Gb (Assuming ulimit, filesystem settings & physical space allowed); GNU tar and most current Unixen allow larger files.  Check `man tar` for your OS and version

I don't see how "Is there a limit on the target .tar file size itself" differs in meaning from the original question

It depends on the followings :
1) Does your OS support large files?
2) What version of tar are you using?
3) What is the underlying file system?

You can cheeck /usr/include/sys/features.h for any line containing 'FILE_OFFSET_BITS'. If there
is, your OS very very probably has support for large files.

If you OS doesn't support large file, you have 2GB limit.

The size of files you put into a tar archive (not the archive itself)
is limited to 11 octal digits, the max. size of a single file is 68 GBytes.

The OS native tar command has the limit of 2GB, the GNU tar
can handle large files as long as your OS and filesystem type support it.

POSIX standard does not allow files larger than 2G into .tar file. Most systems do allow.

Thanks for all your help and answers. From the responses, I gatjer that max limit for 1 file is 2 Gb safely and max size for the whole archive is 66 GB This is very useful
