Centos – Delete original tar after untar? Not enough space to untar

centostar

I have a 130GB tar file I need to untar to /storage.

Problem is, I don't have enough disk space for both to exist at the same time. How can I untar the tar file, and ensure there is enough disk space, and delete the file immediately after untar?

Thanks.

This one is hard. It really depends on how much free space you have.

Others said to extract part of the files and delete them from the tar. That's the only option I can see right now.

Updating the tar requires the tar to be reconstructed without the deleted files on the same drive. That's why you have to have 2 x tar size + something more to allow extraction of the files.

You are on the right track, renaming the file is an atomic operation, so performing the rename after upload is simple, elegant and not error prone. Another approach I can think of is to use lsof | grep filename.tar.gz to check if the file is being accessed by another process.

Mysql – Ran out of disk space, how to tar without creating copy

Use the mysqldump utility to direct the file wherever you like:

mysqldump -A -u[username] -p[password] > /path/to/dest/backupname.sql

If you need to, you can pipe the output through gzip:

mysqldump -A -u[username] -p[password] | gzip -c > /path/to/dest/backupname.gz

Further, you can send the output from gzip to another server via ssh:

mysqldump -A -u[username] -p[password] | gzip -c | ssh user@192.168.0.1 'cat >  /path/to/dest/backupname.gz'
