Here's a quick "Getting Started" guide for HashBackup. Run these commands on your own system to get a feel for using HashBackup, then read the online documentation for the details. For this example, hb-1538-mac-64bit.tar.gz was downloaded from the HashBackup Download page to /Users/jim. Here we go! What's in the tar file?

Adjust accordingly. * the dest verify command does faster & cheaper remote verification, but is less thorough * log all output to /hbdata/logs with timestamps for every line SENDING BACKUP DATA OFFSITE One of HashBackup's strengths is sending backups offsite to protect against disaster. Since disk space is cheap these days, it is recommended that you keep a local backup on site as well as having a remote offsite backup. Keeping a local copy makes HashBackup operations more efficient, especially if you lose a disk and have to restore a lot of data. If you don't want to keep a complete local copy, use the cache-size-limit config option. To setup remote backups, a dest.conf text file is created in the backup directory. The Destinations page has more information and examples for many different storage systems such as Amazon S3, Google Storage, Backblaze B2, and others. For this quick start, we will continue to use the testbackup backup directory and newfile data file we created earlier. Here we go: What's in the backup directory now? [jim@mb hb-1538]$ ls testbackup HBID arc.5.0 cacerts.crt dest.db hash.db hb#1538 hb.db hb.lock inex.conf key.conf That file arc.5.0 is the backup data file created by the backup command. Arc files contain compressed, encrypted user data. Let's setup an Amazon S3 destination first. To do this, go to http://aws.amazon.com and create a free trial account. At some point you will get an access key/id and a secret key. These are your S3 access credentials. Only the secret key needs to be protected; the access id is like a user id. Now we use those to create a HashBackup destination. Your S3 "bucket" name must be unique worldwide. It's a good idea to use the dir option to separate your different backups within 1 bucket. [jim@mb hb-1538]$ cat - >testbackup/dest.conf destname s3 type s3 accesskey xxxaccesskeyxxx secretkey xxxsecretkeyxxx bucket somerandomuniquename dir mb ^d (use control d to exit) Backup the doc directory again (we deleted it earlier with the rm command). Notice the lines about copying to S3. HashBackup creates a new arc file for this backup and copies all backup data to S3, including arc.5.0 from an earlier backup. Now there is a local copy of the backup (in testbackup) and a remote copy on S3.

Here's how to add a Google offsite backup: 1. Go to the Google Storage web page, https://cloud.google.com/storage 2. Create an account 3. Go to your Google Console 4. Go to the Google API section 5. Look around until you find Simple API key or Developer Keys (Google keeps changing the site) 6. You need 2 things: an access key and a secret key. HB does not use OAuth; it uses the S3-compatible interface. 7. add the Google destination to your dest.conf [jim@mb hb-1538]$ cat - >>testbackup/dest.conf destname google type gs accesskey mygoogleaccesskey secretkey mygooglesecretkey bucket uniquegooglebucket dir mb ^d Now do another doc backup.
