USAGE: | |
rotate-file.sh /FULLPATH/ | |
This script checks if the specified backup file exists, | |
if it was modified within a specified amount of days (default=1), | |
renames the file, appending the current date to the end, | |
then removes any files older than X amount of days (default=10). | |
Must provide full path to file. | |
OPTIONS: | |
-r Specify Rentention period in days (default is $RETENTION) | |
-h Specify healthchecks.io URL to ping | |
-a Specify expected age of file in days (eg. if backup is done weekly, specify 7 days. Default is $FILEAGE) | |
EXAMPLES: | |
$ rotate-file.sh /path/to/file | |
$ rotate-file.sh -a 7 /path/to/file | |
$ rotate-file.sh -h https://hc-ping.com/your-uuid-here /path/to/file | |
$ rotate-file.sh -r 30 https://hc-ping.com/your-uuid-here /path/to/file | |
