Description
Hi,
some comments on 'http://docs.mongodb.org/manual/tutorial/backup-databases-with-filesystem-snapshots/':
- section 'Backup and Restore Using LVM on a Linux System', subsection 'Archive a Snapshot', I am reading 'dd if=/dev/vg0/mdb-snap01 | gzip > mdb-snap01.tar.gz': why .tar ? This is not a tar file, should we not read 'dd if=/dev/vg0/mdb-snap01 | gzip > mdb-snap01.gz' instead ?
- section 'Backup and Restore Using LVM on a Linux System', subsection 'Restore a Snapshot': same as above for 'gzip -d -c mdb-snap01.tar.gz | dd of=/dev/vg0/mdb-new', and if not fixed for some reason, you might want to update 'Uncompresses and unarchives the mdb-snap01.gz into the mdb-new disk image.' which correctly refer to a file without '.tar'.
- section 'Backup and Restore Using LVM on a Linux System', subsection 'Remote Backup Storage': same as above.
- section 'Backup and Restore Using LVM on a Linux System', subsection 'Remote Backup Storage': the procedures described in this section use lot of bandwidth, is it done on purpose (remove CPU usage on the server serving the database) ? A note might be welcome to explain the trade-off between doing local and remote compression/decompression.
Feel free to contact me fore more information.
