![]() If the storage backend has not been initialized before, it will initialize To connect to the storage backend specified by the storage url. The init command assigns the given host id that will be used by the backup command later. temp-dir DIR directory for storing temporary files e, -encrypt encrypt to the storage with a master password c SIZE, -chunk-size SIZE the size of chunks (default is 1M) Storage_url the url of the storage to back up to Host_id a unique id to identify the host machine print-stack print the stack trace on error ![]() disable-script don't run scripts before and after the command h, -help show this help message and exit Restore restore virtual machine from previous backup The -email option can also be provided to the cron command to enable email notifications for a scheduled backup jobīelow are all the commands and global options supported by Vertical Backup: usage: vertical īackup back up virtual machines to the storage Vertical email 587 username password when we can run the backup command with the -email option. To set up email notifications, first run the email command: We can also provide the time in the hh:mm format to schedule a daily backup job. This command sets the virtual machine vm-ubuntu to be backed up 10 minutes after every hour: The restore command restores a virtual machine to a previous revision: We can list previous backups using the list command: Vertical Backup assigns increasing revision numbers to backups, starting at 1 for the first backup. This is to back up the virtual machine named vm-ubuntu: Now we are ready to run the backup command. Multiple ESXi hosts can back up to the same storage, and in fact this is the recommended way as this enables cross-host deduplication. Each ESXi host should have a unique host id.īackups will be uploaded to 192.168.1.100 via SFTP with the username being esxi and the storage directory will be storage (relative to the home directory). Vertical init esxi55 we use esxi55 as the host id. Once we have the executable ready, we first need to choose a host id, and the storage to back up to: Mkdir /vmfs/volumes/datastore1/verticalbackupĬd /vmfs/volumes/datastore1/verticalbackup It is recommended to download it to a datastore directory: So by now we can see that ssh -t 'command1 shell' pattern works the best.Vertical Backup is provided as a single executable file. Problem ? -o option SendEnv must allow that specific variable that you are trying to send in /etc/ssh/sshd_config, and besides in either case you still get to run all that stuff with /bin/sh -c Or ssh localhost -t " PROMPT_COMMAND='who unset PROMPT_COMMAND' bash " Problem is this variable has to be exported to the remote server, and Gilles answer helped me to do something like this: ssh -o SendEnv=PS1 ssh localhost -t bash This very nice bash variable runs command each time before showing your PS1 prompt, so why not set this variable before spawining bash to PROMPT_COMMAND="who unset PROMPT_COMMAND" so that we run it as single-shot? Second idea that i had is the PROMPT_COMMAND. Not unless you copy the dot file over to remote server with scp or rsync. bashrc, could one make it use client's local file on the server ? Well,no. My first idea I had is this : if the shell uses server's local. Essentially, there is no way to run a command before interactive use ( unless it is in one of the dot files ) or get an interactive shell from the single-shot command sh -c (or whichever shell it may be, not necessarily sh ). The first one lets you run whatever you put into the stdin while sourcing the dot files, while second just executes those commands and exits. When you run ssh -t "command1 command2" you basically get /bin/sh -c 'command1 command2'. When you login simply as ssh you get interactive version of the shell. This goes back to the basic behavior of any shell. TL DR: int_ua's answer is the way to go, simplest and effortless. Is there a way I can run who automatically, without closing the connection afterward? This connects, enters my password automatically, and runs who, but then closes the connection. Takes hostnames defined in ~/.ssh/config asĮcho "Connecting to hostname -f ssh 'who' This works, so I added who to the end of the ssh commands: Takes hostnames defined in ~/.ssh/config asĮcho "Connecting to hostname -f ssh "Connecting to default host" bash_aliases file to streamline the connection and password entry: There are several servers to choose from in the lab, and I want to be able to automatically run who as soon as the connection is made, so I can see how crowded the server is, and use another one if it's pretty full. Sometimes, when there are lots of other students logged in to the server, the connection is slow, and I lose work during connection timeouts. I connect to my school's Linux Lab frequently to work on my programming assignments remotely.
